Heres something I wrote on Facebook. This was a specific response to a challenge by another poster on Facebook, but its relevant here. In addition to the NDE evidence, the fact is that all these other areas have great evidence as well, these other areas being 1) Re-incarnation (the evidence is beyond compelling as numerous University studies show) 2) Dr Julie Beischels double blind study of hundreds of mediums (found accurate. Alex interviewed her actually. 3) The testimony of thousands of period out of body (OBE/Astral) travelers. They report other realms just the same as those who experience NDE's, and they do so in a cohesive and consistent manner 4) The experiences people have had in every area of the world since man began with ghosts. 5) Quantum Physics 6) The research into Psi. Then we have 7) below (All of these lines of evidence are aligned with each other
There have been studies, Penny Sartori's is the one I'm most familiar with, where they asked people who have been resucitated, "after you were dead, describe to us your resucitation." Those claiming to have an NDE described their resucitation generally very well. Those that did not, generally said something like the following, "What do you mean, I was dead." They told them to "try anyways." They did did absolutely terrible. They couldn't explain anything with any accuracy whatsoever. That's the first point I want to raise. The second point I want to make, is directly relative to your first post. Namely, how do we know that NDE's aren't dreams.
How can we know that NDE's are not hallucinations? Several reasons. I want to outline a handful, but there are more than the ones which I will be listing.
1) Shared Death Experiences
These are experienced by people who are completely healthy who just so happen to be near somebody who is dying.

2) The Blind seeing for the first time during NDE's, and the deaf hearing for the first time. There are several reports and testimonies of this.

3) Veridical NDE's
People floating outside their bodies (often to other rooms) to report conversations and events which later check out as accurate. There are a great deal of these on record

4) These events are life altering. People change permanently. They report a non-existence of time. Those are two (there are many more) rather bizarrely common reportedly themes of NDE's. This doesnt fit the notion that they are Hallucinations, which are disorganized and bizarre and rarely make sense, and generally have no typical after effects. In contrast, NDE's are reported as being more real and clear than everyday real life, and that they make every day existence seem like a mere dream. This is nothing like a hallucination or dream.
5) People very frequently encounter dead people during their NDE's. Notice, they're not meeting living people. Strange coincidence if its a dream that all the people they run into just so happen to be dead isn't it? And why are people hallucinating something which is like what we would think the afterlife would be? Why arent people hallucinating their 57 Chevy? Why are there profound and intelligent moral lessons which are learned? Why this undescribable state of love expressed during these experiences? Sounds a lot like what we would expect an afterlife to be based upon the religious writings of the wise man, sages, holy men, and shaman of the past.
6) There are a lot of reports of people given information about the future, which eventually came true
7) Miraculous healings which people were told would occur during their NDE's, and actually occur
