I was reading Kevin Nelson and he cited a study here http://www.anesthesiaweb.org/images/hypoxia/Lempert-1994a.pdf, syncope & NDEs by Lempert Brauer & Schmidt. Does anyone know of a source with actual interviews of the patients? The table recording the frequency can be quite misleading, DMT hallucinations will tick many of the boxes but when you listen to a DMT trip vs an NDE you can easily tell they are very different. Also has there been any further studies to corroborate this study? I see skeptics persist in using lack of oxygen as an explanation despite the obvious problems like dizziness/unclear fragmented memory, they were probably thinking of this study. I would like to see any corroboration and interviews with the test subjects on what they actually experienced. Skeptic input from @malf @Paul C. Anagnostopoulos are greatly appreciated, if you guys know of interviews/further studies.
