One of the theories put forward by some people to explain the near death experience is that it is a kind of defence mechanism that our mind uses to protect us and help us cope with death.
The brain in some way creates this near death illusion, and in doing so helps us deal with the impending death.
Another theory is that because we were resuscitated we were never really dead.
Therefore once again it is only our mind playing an illusion on us to help us cope with whatever situation we were dealing with at the time.
Another theory is that the near death experience is an hallucination caused by oxygen starvation to the brain.
But due to the fact that many near death experiences involve no situation where the brain has been starved of oxygen this theory is mostly disproved.
Another theory raises a very important question.
How is it that when people have a near death experience there spirit body is wearing clothes.
After all, did the clothes astral travel as well?
If we thought up the astral clothes then did we also think up the whole experience.
