Near death experiences?

Is all this recall just an over reacting dying mind? We have this strong desire to live so, is that what these near death people really saw? All those chemical changes appearing as lights...
Answer:
Hypoxia(lack of oxygen to the brain) has been known to induce NDEs

You might want to look into neurotheology. There are scientific explanations for religious experiences(abnormality in the temp lobe) and NDE as stated above
You can also induce out of body experiences by stimulating the right angular gyrus. Does that mean that you really left your bod? Or that maybe your brain made u think so?

i know the brain releases chemicals similar to LSD upon death, perhaps its a hallucination brought on by the release of these chemicals

I haven't experienced it myself, but friends have. One said she was floating over her body on the operating table. Another was in a coma %26 said he was in a white room with a bright light %26 remembered everyone who was there %26 what they said. He was in a coma %26 remembered everything.
