See No Evil Hear No Evil

This video was posted in the past few days and is a presentation by Sam Parnia and one of his researchers, Tara Keshavarz Shirazi.

The presentation focuses entirely on the output from the qualitative research they have done on NDEs, or REDs. I suspect this was the same dataset they used for their AWARE II paper. The presentation appeared to occur in a room in NYU to other researchers. I think some of these are NDE researchers as they seemed familiar from previous meetings. I will try to be kind, but it’s not easy.

With regard to the quality of the research, I was gobsmacked. The dataset was basically the first 43 NDEs from a set of “exceptional’ experiences from Jeff Long’s NDERF site. Given this is the “selection” criteria it is hard to take it seriously. Why?

  1. The NDEs from NDERF are all NDEs that have been uploaded by people self reporting their NDEs.
  2. Presumably the 100 exceptional NDEs were selected on the basis of their outstanding content. However, these criteria seem subjective at first glance.
  3. After all this time, why have only 43 been looked at? Parnia said that there would be an acceleration now?

There is absolutely nothing scientific or academic about this approach towards selection. This is no different from any of the books by NDE authors. I know why they are doing it…they do not have enough NDEs from their prospective studies, but by using NDEs off the internet as the basis for their information, they completely undermine the “scientific” credibility of the research in my opinion.

As for the research itself, they have developed the narrative arc presented in the consensus paper and AWARE II, which consists of a number of themes such as leaving the body, travelling to a destination etc. These are then broken down into a number of subcategories. I have no problem with this, and their work teases out a lot more detail about common elements of NDEs.

Parnia talks about memory circuits being wiped out during induced coma, and that experiences that patients have while they have moments of consciousness as their coma becomes less deep, meld with memories they have from their time during death. He talks about the memories collapsing into one memory and that we need to differentiate memories that occurred on the ICU ward from those that occurred while dead. Fine so far. Then he uses a specific example – when a patient has a moment of transient consciousness and tries to remove their breathing tubes, they are held down by nurses, and that the patient experiences this as a “bunch of evil people trying to attack them.”

This is how Parnia dismisses all Hellish accounts. He makes the assumption that ALL negative NDEs are the result of ICU experiences or something similar. In the consensus paper he cites a study by Cassol to support this position claiming that the phenomenology of negative NDEs is completely different from classical NDEs, which is in fact entirely the opposite of what Cassol concludes! I make much of this in my recent book…Did Jesus Die For Nothing, and discuss it in a podcast I took part in recently which will be available next week. This is extreme confirmation bias – Parnia will not see or hear evil. It exists, but he refuses to acknowledge it and dangerously is trying to exclude negative NDEs from future research.

In my view this is utterly outrageous, and I am not alone in thinking this. At a later point in the presentation he showed data from these 43 “subjects” that 90% encountered a being of loving light (this is much higher than previous percentages I have seen quoted). Parnia and another researcher toyed with the idea with making this one of the qualifying criteria for an experience to be classified as an NDE. A different attendee piped up at this point and said she would be very concerned about accidentally disqualifying what may be very important experiences by using only these positive criteria. Parnia basically ignored this objection. I am not just concerned, I am very frustrated. Parnia is trying to impose his own bias on the direction of future research, and in doing so may be missing important lessons from NDEs.

There was another point where Parnia’s approach was challenged by an attendee. Parnia was saying that people are all experiencing the same thing but are using their cultural background to interpret what they see differently. Again, this is an assumption arising from Parnia’s bias, and the other attendee used an analogy to describe his issue with this. He said that everyone in that room had been on a journey that morning to get to that room in New York, and while there were commonalities such as mode of transport etc, there were also differences such as route and what they observed. These differences weren’t just subjective differences, they were objective differences, and that by trying to impose generalities on the experiences, there was a risk of imposing your own bias as you developed a theory. The point seemed to be lost on Parnia. I will expand the analogy that the other attendee made.

Let’s say there were ten attendees and they were all new to New York. 5 took taxis, 3 drove in private cars 1 came by bus and 1 came on the subway. All took a form of transport – the necessary commonality, but their experiences were different. The ones in the taxis and private cars would have had reasonably pleasant experiences, except for the traffic, but the ones on the bus and the subway may have had less pleasant experiences. Now let’s say the one who took the subway saw a mugging. His experience of travelling in New York would have been negative and he would say New York was dangerous. From a purely objective external position, it is rational to say that New York can be dangerous, particularly if you take the subway. What Parnia is doing is to entirely discount this kind of experience. He is like a tourist brochure which says that New York is safe. Yes, it mostly is, but not always. The objective differences in these travellers’ experiences provide us with vital information about the best, or safest way to travel in New York, and that excluding them would be to exclude very important information based on a biased view that New York can only be safe.

The same applies to NDEs. Hellish NDEs exist. They have the same phenomenology as positive ones, except people do not have a positive feeling. They experience a sense of timelessness, heightened senses etc. What we learn from these experiences may be extremely valuable and Parnia is indeed trying to impose his own bias of basically “seeing no evil and hearing no evil” on the future direction of research and discussion on the topic.

Also by assuming that all NDEs are essentially the same, and that assuming the differences in reports are due to cultural interpretations, he may be missing the fact that there are differences DUE TO cultural background, or indeed other possible explanations – which I explore in great detail in my latest book. What if NDEs are SUPPOSED to be different and create confusion? That is what I explore in Did Jesus Die For Nothing?

RIP Peter Fenwick

Sadly (for us left behind), Peter Fenwick left this earthly dimension last week.

Anyone who has a serious interest in NDEs will have heard of Peter Fenwick and read some of his work. He was one of the early giants of the field alongside Moody, Ring, Greyson and Sabom. He has been on TV and in national newspapers countless times in the UK discussing the incredible glimpses into the afterlife that NDEs provide. Many who visit this blog will have communicated with him in some way and those who have, report only good things.

While his contributions will be missed, and our thoughts are for his grieving family, our hope is that he is now enjoying the best that the next life has to offer.

Get the smelling salts…you will need them after this!

Firstly, thank you to all those who bought one of my recent books. You will be relieved to hear I won’t be banging on about these for a while now! Back to the day job!

This paper was published in July by Charlotte Marshall from Liege University in Belgium. She has a strong research record in the field of consciousness, and her name is attached to many of the papers we may have discussed in the past, and interestingly on both sides of the debate. She has done a lot of work in psychedelics and was author of a paper that is worth a separate review which came out in August and looks at patients who have had an NDE AND psychedelic experience. (I am pretty sure I discussed this in one of the comments sections but will return to it). It is interesting, and there are some flaws in it which are common to all of these papers. It is also worth noting that Marshall is doing her own version of the AWARE study. While I think she definitely lies on the physicalist side of the debate, and is of the view that NDEs are generated by the brain, at least publicly, in my opinion, she does not appear to be of the same level of physicalist fanaticism as Bourjigin appears to be. I find her articles more balanced. Could be a smoke screen of course.

Much of her work focuses on trying to understand NDEs through various analogous brain-driven experiences: epilepsy, psychedelics and in this article induced-syncope (fainting):

EEG signature of near-death-like experiences during syncope-induced periods of unresponsiveness

Charlotte Martial, Andrea Piarulli, Olivia Gosseries, Héléna Cassol, Didier Ledoux, Vanessa Charland-Verville, Steven Laureys, NeuroImage, Volume 298, 2024, 120759,

During fainting, disconnected consciousness may emerge in the form of dream-like experiences. Characterized by extra-ordinary and mystical features, these subjective experiences have been associated to near-death-like experiences (NDEs-like). We here aim to assess brain activity during syncope-induced disconnected consciousness by means of high-density EEG monitoring. Transient loss of consciousness and unresponsiveness were induced in 27 healthy volunteers through hyperventilation, orthostasis, and Valsalva maneuvers. Upon awakening, subjects were asked to report memories, if any. The Greyson NDE scale was used to evaluate the potential phenomenological content experienced during the syncope-induced periods of unresponsiveness. 

What they do in this study is use a technique to induce syncope, which is a state of lower blood pressure/oxygen to the/in the brain which causes a state in which the patient faints for a very brief time (20-30 seconds). The patient is not unconsciousness, but enters a state of “disconnected consciousness”. Their eyes may be open or closed. Their heart is still beating, there is just a sudden alteration in the amount of oxygenated blood reaching neurons due to the physical process they went through. You probably did it when you were a teen…hold your nose and mouth closed and try to breath out really hard. You feel light headed etc etc. Afterwards they then do a Greyson scale questionnaire which everyone on here should be familiar with. I will come back to this. Here are some key quotes from the paper:

This study demonstrates the capability of syncope to induce episodes of disconnected consciousness, intriguingly resembling NDE episodes. Indeed, eight volunteers out of 22 (36 %) reported a subjective experience that met criteria for an NDE-like (i.e., scoring ≥7 on the Greyson NDE scale.

Interestingly, both DMT- and ketamine-induced experiences are known to closely resemble NDE phenomenology (Martial et al., 2019Timmermann et al., 2018), just like we here demonstrate the resemblance of syncope-induced dream-like states with NDEs.

I will return to this in the next paper that I review in the coming weeks. I did review this paper in August, but as I said there has been a new paper that is really worth critiquing.

The hypothesis that the subjective experiences, as well as the associated pattern of electrical activity observed in this study, occur also in people who report a classical NDE in severe cerebral hypoxia is appealing but remains an open issue. 

I don’t really think so as I will discuss below, but for someone from the “dark side” I approve of this use of language. It is neutral.

When it comes to this study there are three main issues (I’m sure I will think of more once people start commenting).

1.The first is something I now really agree with Sam Parnia on…this is “abuse” of the Greyson questionnaire, which was specifically designed for assessing people who had died and been revived long before serious research had been conducted in the field by skeptics. Many of the questions use descriptors that are so vague they could apply to any unusual state…even walking in a forest in a meditative state. To say that someone has had an NDE-like experience just because they score above 7 on the Greyson scale is now becoming a bit of a joke. This is the type of spurious assertion that is applied when the Greyson scale is used in psychedelic research. Marshall and Timmerman try to overcome this in the paper they published in August which I will review next time, but they don’t…as I will show. The experiences from NDEs are very very different when it comes to the kind of subjective experiences they describe. For instance here is an excerpt from a different study, cited by Marshall, from someone who had a syncope induced experience. Does this sound like anything that someone who has an authentic NDE would say?

    A 48-year-old male patient was admitted for the diagnostic investigation of paroxysmal events. He experienced his first episode at age 46 when he felt “funny for milliseconds” while playing badminton. He lost consciousness immediately and fell. When he regained consciousness after about 3 min, he hallucinated many persons of small size (“like seeing them in television”) who were “parading like soldiers.” He could vividly hear their heavy steps.

    Christian Brandt, Out-of-body experience and auditory and visual hallucinations in a patient with cardiogenic syncope: Crucial role of cardiac event recorder in establishing the diagnosis, Epilepsy & Behavior, Volume 15, Issue 2, 2009, Pages 254-255

    I am leaning toward the term RED after all!

    2. The EEG data is of a completely different type to that previously described by the likes of Borjigin in that it is not gamma, but beta, delta and theta. This is in line with psychedelics from my memory. It seems that there is as yet no consensus on exactly what EEG signals are specifically indicative for consciousness, dissociation etc. Until this is better understood, claims of EEG activity being indicative of consciousness immediately after CA or during CPR should be taken with a gargantuan pinch of salt.

    3. Lastly, while all this is very interesting, I have yet to read of a veridical OBE from one of these types of study, in which a respected doctor confirmed that a subject observed things that were impossible for that patient to observe naturally. Of course, if they did, then this would actually prove dualism, although I’m sure hardened skeptics would try to create some quantum mechanical hypothesis to hide the naked truth behind. Titus Rivas created an excellent collection of these veridical OBEs in his book the Self Does not Die. This collection forms sufficient empirical evidence to support the dualist hypothesis and reject the physicalist hypothesis.

    What may be happening with all these “NDE-like” experiences is that the brain is being sufficiently disrupted that it momentarily experiences “other dimensions” or states of consciousness that are much more advanced once the consciousness actually leaves the body in an authentic NDE. That is all speculation though. My immediate concern is Marshall has a strategy here to develop an ” scientific evidence-based” narrative around the hypothesis that ALL NDEs are a result of altered brain states, and that around the time of CA just such an altered brain state creates the NDEs that people report. I am very concerned that she has set up her AWARE-like study purely to reject the Dualist hypothesis, which would be easy by under-powering it, but using jargon to confuse the wider scientific community and media into believing the evidence is conclusive. My “prayer” is that she will be surprised and end up generating at least one verified OBE that supports the dualist hypothesis – this would of course give Parnia an aneurism after spending 20 years trying to achieve that! But in all truth, unless a higher power is involved, there is a miniscule chance of her study producing a verified OBE for reasons we have discussed here before

    My Latest Non-Fiction Book Kindle Version is Free for 48 hours

    Thank you if you have already bought DJDFN and paid…your support is very much appreciated. Also thank you to those who have given 5 star reviews at this point (more please if you feel it is good enough 🙂 ). Remember 5 stars is good, 4 stars average, everything below that is not good. If you really think it is a steaming pile of doodoo and want to warn people off buying it, then of course must do what you must, but every negative review is a killer. Reminder, if you really object to Christian teaching…DO NOT GET THIS BOOK, it will only wind you up. But if you are already a believer or open to the idea that Jesus was exactly who the gospels claim him he was, then you may well enjoy it.

    This is now free on Kindle until midnight Pacific Time Sunday. After this post, and provided something of interest pops up, I will no longer be using this blog to flog my books (well maybe occasionally…but not like I have done the past few weeks).

    Did Jesus Die For Nothing?

    Another week another book launch.

    Try the link below if the above doesn’t work, or go to your local market and search under my name – Orson Wedgwood:

    https://mybook.to/DidJesusForNothing

    This book really focuses on what NDEs mean for the Christian understanding of who goes to heaven. A few things to consider before you buy:

    • The first half of the book is a condensed and an updated version of my NDE AWARE book. So if you bought that just be aware this is the case. I am planning on launching an abridged version in the New Year which just focuses on the religious side of it.
    • The Kindle version is currently priced as low as possible to be able to take advantage of various deals. I have also heavily discounted the paperback price on Amazon to $5.99 US and £4.99 which means I literally make about 20 cents a sale! This will go up by a dollar or so once I have some reviews under my belt…so please post some reviews!
    • This book is biased!! It is aimed at those who are already Christian or who are really interested in Christianity. It presents a case for what Jesus says about those who will go to heaven being true, in contrast to what many in the NDE community say. There is some really fresh thinking here on that topic. I do not for instance say that all non-Christian NDEs are demonic as some do. I believe my take on this is unique. Moreover, any position on this will be due to anyone’s bias since the data is contradictory, so I deliberately deploy Christian confirmation bias but provide a strong rationale for my final understanding. If you are hostile to Christian beliefs…do not bother buying this book, it will only annoy you!
    • Lastly, if you still decide to buy it, I really hope you enjoy it. I delve into the nature of existence and the meaning of life…all for the price of a cup of coffee (and a Muffin if you buy the paperback). If you enjoy it, then please please review it and rate it

    My Novel is free on Kindle for 48 hours!

    Apologies for another post about my book(s), but in the absence of any exciting NDE research news, for the next couple of weeks while I am launching my latest writing efforts, this will be my focus.

    From now until Sunday midnight Pacific Time I am offering my novel, Unholy Spirit free on Kindle (if you don’t have a Kindle the APP is available on Android or IOS). If you do download it and enjoy it, please write a review on Amazon or at least rate it. To get it click on the BUY button, or BUY ON AMAZON tab. The price should be 0.00…what’s not to like!

    Hope you enjoy it, and if you do, remember in the world of net positivity scoring 4 stars is now average to good and 5 good to great. This is obviously my attempt to kick start sales in the first week, and if you appreciate my writing here, this is a great opportunity not just to download a fabulous book, but to support me in a very real (and cost-free!) way.

    The non-fiction book will arrive in about 10 days time, so you can read this between now and then 🙂

    My Novel is now available

    Given the title, I almost feel like I should wait till Halloween, however, it is ready and good to go and available in all Amazon markets as Kindle or paperback. It is not a horror story, although there may be some bits that are a bit scary! The genre is difficult to nail down – it is a spiritual sci-fi urban fantasy adventure! It is set in this world, in this time but incorporates the spiritual and also extra-terrestrial. It is not a full length novel, but a good sized half length (48k words). The second part, which will complete this novel, will be available some time next year. The more positive reviews I get and the more sales I make will determine the speed at which I write! I will be doing a Kindle countdown deal next weekend and heavily discounting the Kindle version to encourage purchases and reviews (not possible with the paperback), but if you like what I do here, and want to support me, then please buy it at full price. If you’re a bit skeptical about it, then wait till the weekend!

    A former member of this blog, who shall not be named, wrote to me privately when I first mentioned this book, and was quite discouraging. Others were encouraging (thanks especially to Anna). Over 10,000 copies of the PDF of the first few chapters I put on here were downloaded and the poll was positive.

    I actually wrote a version of this back in 1995, I then put it aside for many years focusing on work and other projects. While I would not say it is entirely original in that it ventures into NDE territory, I think that books are like pizza. Just because Pizza isn’t original, doesn’t mean that a new pizzeria can’t open up and sell pizza!

    The blurb:

    Mark Howland, a neurochemist specialising in psychedelic research, is desperate to overcome the grief that seared his soul when his wife died. He makes a drug that he believes will allow his consciousness to leave his body so he can see her again, but a catastrophe cuts his plans short.

    Helen Richardson,former corporate spy, had a Near Death Experience that rocked the foundations of her worldview. She is determined to prove whether it was real, and Mark’s drug may be the path to achieving this, but first she must get her hands on it.

    Her obsessive quest to learn the truth about what happens beyond the edge of life comes up against powerful forces, both seen and unseen. Her quest turns into a fight for survival and for humanity’s freedom.

    If the above link doesn’t help, then click on the link below which should direct you to your local amazon market.

    Link To Unholy Spirit: Part 1

    If you do read the book, and you enjoy it then please review or at the very least rate it (remember 4 stars is now average and 5 stars good. 3 stars or less is bad). If you really hate it, please consider carefully the impact a negative review will have. Each negative review is inversely proportional to 10 positive reviews. I have worked hard and already spent quite a bit of money to get to this point. At the end of the day if you really feel readers need to be warned off buying it, then place a negative review. Also, if you spot any typos or mistakes etc, please let me know in the comments or PM me. It has been copyedited professionally, and proof read by the missus and me, but there will still be mistakes!

    The non-fiction book I have been working on will land in about 2 weeks time.

    A different Ketamine of Fish?

    Sorry for the awful pun…couldn’t resist it though. I promise nothing so bad appears in either of my books (the novel is coming out tomorrow!)

    This is really a footnote to the post I did on psychedelics and is the result of a conversation I had with an ER doctor. He is part of a group of intellectuals I recently started meeting with who discuss some of the deeper issues of life…much of it way too deep for me in fact, especially when it comes to theoretical physics etc. However, we got to discussing NDEs and OBEs and he told me that just a week before he had a phone call from a surgeon who had been performing an operation on his mother (the ER consultant’s mother). The mother had listed in her notes that she has a reaction to Ketamine, and yet the team had still used Ketamine as an anesthetic. Her reaction is that she experiences a full blown OBE. Having received the Ketamine, and had this reaction and still conscious, the surgeon had phoned this woman’s son to calm her down as she was freaking out. He was literally talking to her while she was on the operating table experiencing an OBE. Was it verified? No. Was it a true OBE, or some form of illusory autoscopy in which the brain tricks the person into believing they are seeing themselves? Impossible to know without doing an experiment designed to test this. I will mention it to the doctor next time I see him, but it is highly unlikely his elderly mother would willingly undergo the experience again as it terrified her.

    So I did a bit of looking into this, and OBEs with Ketamine are a relatively common phenomenon. The mode of action of Ketamine is quite different from psychedelics and causes dissociative experiences. This paper written by a group from Ryerson in Canada describe the incidence of OBEs.

    https://pubmed.ncbi.nlm.nih.gov/21324714/

    I contacted the author of the paper to ask if any further work had been done to try prove OBEs, and he said that there hadn’t been and that the phenomenen was almost certainly neurologically induced.

    For me the key is complete lack of veridical OBEs for Ketamine induced OBE-like experiences. Given its widespread use in medicine, if the OBEs were true OBEs, then you would have hundreds if not thousands of veridical OBEs – as we do with NDEs.

    In conclusion, I do not believe that Ketamine causes genuine OBEs.

    An attempt to disprove NDEs?

    This Daily Mail article (thanks Michael and Pablo) contains one tidbit of information that is very useful:

    https://www.dailymail.co.uk/health/article-13907689/scientists-state-life-death-neuroscientist-experience-unbearably-intense-icy-blue-light.html

    “Charlotte Martial, a neuroscientist at the University of Liège in Belgium, who co-authored the study, is now trying to verify patients’ claims about their out-of-body experiences during NDEs.
    Around eight in ten people who’ve had an NDE report leaving their body, sometimes stating facts about their environment that they seemingly should not know.
    To test this, Dr Martial has decorated a resuscitation room at Liege University Hospital with unexpected objects and images, some of which are hidden in places that could be viewed only from the vantage point of someone near the ceiling – she is then asking patients who report NDEs if they’d noticed anything unexpected in the room.”

    I mention this study in my soon to be published non-fiction book. Martial is not doing anything new here, and her study is much smaller in scope than Parnia’s, so it begs the question as to why she is doing it. I have my own theory on this and it is related to the fact that Martial is on the physicalist side of the debate. It is also related to the scientific method and the fact that for those who are into the semantics of this you can not prove a hypothesis to be true, you can only disprove it, or provide experimental evidence to support it. This is because there is always a potential unknown alternative explanation for a phenomenon. In reality we accept that hypotheses are proven true all the time, but for those who are pedantic about these things, it is is not technically correct.

    Given what we know about the difficulty in validating OBEs – for instance Parnia reckons we would need tens of thousands of in hospital CAs to get one validated OBE – it is easy to devise an experiment that could disprove the hypothesis that “NDEs are a result of the consciousness leaving the body after death”. Here is how you would do it. you would start with a statement based on this hypothesis that says the following:

    “If NDEs really are a result of the consciousness leaving the body, and 1 in 10 people who have CAs and survive have an NDE and 8 in 10 people who have NDEs report leaving their body (I will come back to that), then if 100 people die and are resuscitated, 8 of those people should leave their bodies and report observations from a room filled with secret images.”

    So, you wait till you have 100 people survive CAs and no one has reported seeing an image, you can say you have disproven the hypothesis. That is almost inevitable because only 25% of NDEs have OBEs, and even then they may not remember seeing the image.

    This, I believe is Martial’s game. It will take her a long time since if she is only using 1 ER suite then getting 100 survivors will take years, as we know. Also, there is an expression that you may have heard “the devil always overplays his hand”. I suspect she may end getting a “hit”, which will be galling for poor old Dr Parnia! I just hope she has the humility and scientific integrity to report it if she does. It would be so much more convincing coming from her than Parnia since she is a sceptic.

    Lipstick on a tripping pig

    After months of promising, I am finally posting this article about Psychedelic’s and NDEs. The reason that I have been kicking it into the long grass is twofold. Firstly, I always have seen and still see, data from psychedelic trips as inconsequential in terms of challenging the validity of NDEs, as you will see, and secondly there is a lot of data to review, although I have decided to focus on one paper by Timmermann from 2018, and the 2022 Parnia consensus response, and some of his invective from his book Lucid Dying.

    Interestingly I may have been in a position where I would not have been allowed to write about this. Last December I was in discussions around joining a company who were in the pre-launch phase for a psilocybin derivative for treating depression as their European medical scientific lead. I had reviewed the literature and was in two minds about the risk benefit ratio of the drug, and a little frustrated by the complete lack of reporting of “subjective” effects from the studies as I suspect the perceived nature of the subjective effects might actually have had an impact on outcomes such as suicidality. No matter, I didn’t get the position (good job as the recent FDA advisory committee came out against deploying psychedelics in healthcare at this stage).

    Now on to the subject. The paper that I focus on and is of most relevance is the one by Timmermann et al published in Frontiers in Psychology, not a premier academic journal. In this paper 13 patients took DMT and were given the standard NDE questionnaire afterwards. This was compared with a baseline questionnaire reflecting their non-“tripping” state, and with matched controls of people who had “authentic NDEs”.

    One very important point to consider here is the fact that only 13 patients took part and they were selected through “word of mouth”. Ultimately, in my view, anyone volunteering through “word of mouth” recommendations to participate in a study taking DMT has a certain level of baseline “abnormality” that sets them apart from the normal population. Also using such a small number of patients makes it of low value in terms of the “meaningfulness” of any results. In truth, the study lacks any credibility at the outset because of these two points and would exclude it from a serious peer-reviewed journal due to this, but let’s car park that and consider what it says.

    This is the key finding:

    “All participants scored above the conventional cutoff (above or equal to 7) for a (DMT-induced) near-death (type) experience (Greyson, 1983). One of the 13 participants had a total score of 7 following placebo.”

    The fact that one patient out of the thirteen reported an experience of greater than 7 on the NDE scale on placebo is very pertinent and speaks to the patient selection criteria…to be polite, they were probably not a representative selection of “normal” people.

    Below is a graphic of the breakdown of scores for the patients on placebo vs the same group of patients on DMT:

    Now here I am going to depart to some anecdotal experience. I would never admit to taking illegal substances, but I may know someone extremely well…cough cough…who went through a period when they were at University a long while ago and spent about six months consuming a lot of weed. One particular batch of weed that this friend…cough cough…had must have been spiked as he went on a massive trip. In this trip he became a wolf in another world. He was still aware of the fact that he was lying on the floor of his bedsit in Southampton, but at the same time was having this “out of body” experience, with heightened senses – time seemed to slow right down – in another world (unearthly environment), and there was even some religious symbolism…probably a 7-10 on the NDE scale.

    That is the point about the above graphic. This person…cough cough…knew this was not an NDE and yet would have scored over 7 on the NDE scale, and this person…cough cough…was not someone crazy enough to volunteer for a study in psychedelics, and as a matter of fact never bought weed from that supplier again.

    In this study, which is probably the most relevant of its kind, they show that DMT creates an experience that scores the same on the NDE scale as authentic NDEs. However, as this person I knew very well has shown you can have an experience that is not an NDE but scores like one. This says more about the way that NDEs are scored than the value of any conclusions you can draw from this study with respect to psychedelics creating NDE-like experiences. To the author’s credit, this is somewhat recognized:

    “It is important to acknowledge that the phenomenology of NDEs is still a matter of some investigation.”

    This is why the 2022 consensus paper has some value as it seeks to more precisely define the different domains of experience. In that paper Parnia has the following to say in his section on psychedelics:

    “Another major contributing factor that enables some to argue that drug-induced states are similar to so-called NDE involves the misuse of research scales that were developed  for the specific study of so-called NDEs in non-context-specific circumstances, even  though these are not designed for, nor are they sensitive or specific enough to distinguish a classical NDE from other experiences.”

    In other words, the original Greyson scale was designed specifically for NDEs and not for other experiences so using this scale to look at DMT trips makes the findings less relevant.

    Timmermann also cites a paper by another NDE investigator from the sceptic camp, Martial. He says that her work showed “that the temporal sequence of events unfolding during an NDE is highly variable between people and no prototypical sequence was identifiable.” This directly contradicts the narrative arc described in the consensus paper. However, on closer inspection of the Martial paper, while there is some heterogeneity in the order of some aspects of NDEs, the suggestion that there is no prototypical sequence is not an accurate conclusion to draw. I may review this paper at another time, but there are confounding factors in the paper to consider such as the fact that not everyone experiences all the elements (she does go a little way to addressing this by looking at reports which contained all of 4 specific common elements but the conclusions are the same for me). However, when you look at the highest percentage of experience reported at sequential timepoints T1-7, you get the following sequence:

    T1-OBE>T2-feeling of peace>T3seeing a bright light>T4encountering people/spirits> (T5&6) coming to a border/boundary >returning to body.

    This is very much in line with the narrative arc. You could argue that because they don’t all appear at the same time point there is heterogeneity, but in reality that heterogeneity lies in the fact that not everyone reports all the elements, and that some elements are not “time-critical” e.g. feeling of peace. Ones that are, such as OBE and return to the body, occur exactly where you would expect in the vast majority of those who report these elements. This points to Timmermann’s “confirmation bias”.

    Parnia seems to have taken a leaf from my book when it comes to using pejorative terms when describing other people’s work. In Lucid Dying he says the following:

    “Dr Timmerman’s claim was just another example of putting lipstick on a pig.”

    Quite.

    However, given that Parnia uses outrageous confirmation bias in the consensus paper regarding negative experiences, something I discuss in my soon to be published book in much greater detail, I will use my own cliché “pot calling the kettle black”.

    All fun and games, and if Sam Parnia ever reads this blog, he will know that we all love him here and will hopefully take our criticism in a friendly way. What he does do an excellent job of in his 2022 paper is to go into a detailed analysis of the descriptions of psychedelic induced experiences vs NDEs and reveals how different they are in reality.

    Ultimately though I regard all of this as a storm in teacup – the main reason why I have struggled to spend 3 hours on a day off prior to now to cover it.

    This is because:

    1. There is not a single veridical OBE validated by an accredited HCP who is prepared to go on the record from a psychedelic “NDE-like” experience. As we know from historical accounts, and the excellent work or Titus Rivas in The Self Does Not Die, there are hundreds if not thousands of these for authentic NDEs that defy natural explanation. In sum, these are incontrovertible proof of the validity of OBEs and NDEs.
    2. If there were veridical OBEs in a DMT experience, so what? All this would prove is that psychedelic drugs can cause the consciousness to dissociate from the brain thereby proving that the consciousness is either independent of the brain, or that the brain is able to project a version of the consciousness beyond its physical confines and observe things that are naturally impossible to observe – mmm.

    Now I know that the likes of Timmermann approach this from the other way round to the way I suggest that they do, namely that they try to infer that NDEs are just a physiological phenomenon induced by neurotransmitters like DMT trips, and not that DMT trips are like NDEs. This is the reductionist approach, but whichever way round you look at it, the similarities are superficial and do not stand up to scrutiny – the pig is most definitely wearing make-up.

    Ultimately my highly speculative view of psychedelics, and while we are on this (and I may do separate posts on these at some point), other NDE-like experiences reported due to syncope or REM intrusions etc, is that they possibly disrupt the consciousness in a way that momentarily causes it to “wobble” within it’s physical confines. This speaks to Parnia’s disinhibition hypothesis (Eduardo – shush) and the idea that there is a physiological mechanism behind the consciousness “packing its bags and leaving” that may be facilitated by certain neurotransmitters. This is highly speculative, but maybe DMT, epileptic fits, syncope etc disrupt the tethers that normally keep the consciousness in place.

    Hope you enjoyed. If you did please buy one of my books or buy me a coffee if you haven’t already,
