The usual crytpo-relgious, go-into-the-light, your-granny's-waiting thing. It was incredibly blissful. The thing that "saved" my life was my evil tongue. I had left my body and was watching them try to resuscitate me. My mother was in the room hysterical. Meanwhile, I was also tripping with the dead, being lead off who-knows-where. It crossed my mind that if I traveled any further I wouldn't be able to come back. Then I heard my mother say something that annoyed me so much I wanted to make a sarcastic reply -- but I knew I'd have to return to my body to do it. Sarcasm being irresistible, I "came back" to make the nasty remark. I most remember the terrible pain I felt "rejoining" my body as I gasped for breath to insult my mother.
I've never decided what to make of that experience. Ironically, years later, Raymond Moody, the psychiatrist who wrote the book on NDEs ("Life after Life"), became my professor. He thinks they are genuine encounters with spiritual realms, but I recall some research a few years back that demonstrated an NDE can be initiated by stimulating a certain part of the brain during surgery.
During the worst years of the AIDS epidemic I sat with many people -- probably a hundred or more -- while they died and there was pretty remarkable consistency to what they reported.
