Your experience is interesting. I am reading the book 'Closer To The Light' by Melvin Morse, MD. He did a study on children in Seattle about 25 years ago.
He says his study proved that a person must be on the brink of death to have symptoms of an NDE: "My findings eliminated the theory that NDEs are the result of drugs or sleep deprivation or that they are merely bad dreams or the subconscious awareness of surgery." ... "Of the 121 patients we interviewed who had survided a serious illness but were not near death, 118 had no exerience at all. The remaining three had dreams of white-coated monsters and the like."
"Meanwhile, eight of the twelve survivors of heart attacks had visions of leaving their bodies and traveling to other realism. That is almost seventy percent, a percentage so high it eliminates the element of chance or statistical error."
The 12 in the study were children that had actually 'died' and were brought back. Not every one of them experienced something - but a high percentage did.
I wish you had experienced more - it would be an interesting story to tell. Oblivion, nothingness, total lack of any consciousness, a deep and dreamless sleep is better than a fiery hell. That's one good thing about being raised a JW - no fear of burning in hell.
Dr. Morse tells the details of the experiences his patients had. Very interesting book. It's making me think about the possibilities.
