There are many aspects of Near Death Experiences that you can't explain neurologically and that have a metaphysical aspect.
How can you explain why a person who is clinically dead with no brain function can later tell things in detail that happened in the operation room or in any other places where he/she didn't have any access to?
Why do individuals who are blind since birth see clearly in Near Death Experiences?
There are many Near Death Experiences of young children which have the same characteristics than those of adults. Are they inventing it?
Every day there are people experiencing this. On the website www.nderf.org there are thousands of Near death experiences recorded of people of all kind of background and religion.
It was said Near Death Experiences are all different. Of course they are different, because they are made by individuals. However most if them have the same characteristics: Being outside of the body, going through a tunnel, a life review, not being able or allowed to cross a border, being with deceased loved ones, feeling unconditional love, being with god, being one with all life and the universe.
Many of those that experience it, tell of a life changing event and they remember it clearly for their whole life as something real, whereas a dream gets blurry.
