Question about the whole NDE concept and Dr. Jeffrey Long

[GUBU]

I am currently an agnostic, and I do believe in evolution, the big bang, I am a big fan of Richard Dawkins, Laurence Krauss, Hawking, just to name a few atheists. I think that for the most part, science does its job when explaining the universe, and the world in general. However, the concept of Near Death Experiences and Out of Body Experiences cause me to scratch my head. Recently, Dr. Jeffrey Long published a book where he analyzed 1600 cases of NDEs and he claimed that they were all strikingly similar, regardless of cultural differences. For example, many people reported seeing a bright light, feeling a lot of love, meeting deceased relatives, having a life review. I am wondering if anyone on this site ever read the Dr. Jeffrey book proof of afterlife? In his book, he even debunks the ideas of the brain hallucinating, and the idea of chemicals being released in the brain to cause these experiences. About 95% of participants thought that these experiences felt more real than real life, and hallucinations cannot feel that real. Also, many claim to see A god, but without a particular title. If 1600 experiences are very similar, would you say that it could mean that these are in fact snapshots of an afterlife? I just don't know how they can be so consistent, and how they can be so life changing if they are not real. 
People, please go easy on me! This is my first day and I am not an atheist, but an agnostic. I just want to know your opinion on Dr. Jeffrey Long, and on NDEs and OBEs in general!
Thanks,

The best "evidence" for NDE's is from Sam Parnia's AWARE study, which changed its goals mid way through the study, because the original test of putting a card with a series of numbers in a place in the room where it couldn't be seen other than an out of body experience was getting no hits, where there was a sum total of one NDE (according to Parnia) which was a man, a year after his cardiac arrest, recalling medical details that he could have gotten from watching an episode of ER (which had all genuine, top of the range equipment, none of it turned on).

I had a good link on the whole thing a while back, but I erased it, and now can't even find the article on google. If I do I'll post a link.
