Semiology and Mechanisms of Near-Death Experiences
Costanza Peinkhofer, Jens P. Dreier and Daniel Kondziella
Current Neurology and Neuroscience Reports (2019) 19: 62

Abstract
PURPOSE OF REVIEW:
Near-death experiences (NDEs) are conscious perceptual experiences, including self-related emotional, spiritual, and mystical experiences, occurring in close encounters with death or in non-life-threatening situations. The origin of NDEs remains unknown. Here, we review recent advances in the understanding of NDE semiology and pathophysiology.
RECENT FINDINGS:
Recent prospective studies confirm that NDEs reflect a spectrum of highly distinctive memories which are associated with negative or positive emotions and can be influenced by the nature of the causal event, but the temporal sequence with which these images unfold is variable. Some drugs, notably ketamine, may lead to experiences that are similar or even identical to NDEs. New models extend previous neural network theories and include aspects of evolutionary and quantum theories. Although the factual existence of NDEs is no longer doubted and the semiology well-described, a pathophysiological model that includes all aspects of NDEs is still lacking.

Would be an interesting read, but the price is too high.

Can ketamine/Dmt be the reason of these experiences? Surely there are some similarities, although often I see that the research focuses on the words used, not on the feelings left on the persons 

Of course people under ketamine feel good, joy too. I had a few friends who really liked that kind of "high". They never gave me the impression they were having some kind of NDE tough. No universal love, no full understanding, no verifiable OBEs. They sometimes felt "like they were out of their body", but NDErs don't just "feel like it", they actually are outside their bodies (at least according to their POW). And no ketamine trip I've ever seen brought significative personality changes and reduced fear of death.

I don't deny it is possible that NDEs are caused by chemicals, unlikely as that is. But I would like direct comparisons between NDErs experience and ketamine. Also, why not have NDErs directly try ketamine and see if it is the same?

That webpage does have links to about 90 additional resources. I didn't follow all of those links, so don't know what is out there, but in at least one case the full text of the linked document is freely available.

It could be a useful list of reference material at the least.

sci-hub is your friend...

Not to speak for Raf, but - to my knowledge, there are studies comparing the effects of DMT and/or ketamine to NDEs, but I've not come across any where people who have had a deep NDE later went on to try these drugs and offer a comparison, or vice versa.

Characterization of near death experiences using text mining analyses: A preliminary study
https://doi.org/10.1371/journal.pone.0227402

Abstract: The notion that death represents a passing to an afterlife, where we are reunited with loved ones and live eternally in a utopian paradise, is common in the reports of people who have encountered a “Near-Death Experience” (NDE). NDEs are thoroughly portrayed by the media but empirical studies are rather recent. The definition of the phenomenon as well as the identification of NDE experiencers is still a matter of debate. To date, NDEs’ identification and description in studies have mostly derived from answered items in questionnaires. However, questionnaires’ content could be restricting and subject to personal interpretation. We believe that in addition to their use, user-independent statistical text examination of freely expressed NDEs narratives is of prior importance to help capture the phenomenology of such a subjective and complex phenomenon. Towards that aim, we included 158 participants with a firsthand retrospective narrative of their self-reported NDE that we analyzed using an automated text-mining method. The output revealed the top words expressed by experiencers. In a second step, a hierarchical clustering analysis was conducted to visualize the relationships between these words. It revealed three main clusters of features: visual perceptions, emotions and spatial components. We believe the user-independent and data-driven text mining approach used in this study is promising by contributing to the building a rigorous description and definition of NDEs.
