I've had one, I didn't experience anything related to any one particular religion. All I remember was being in a huge room with blinding white light, and I could see my physical body below me.
last year, i had a near fatal heart attack (and i'm pretty young, too). when i heard them say, "he's critical" i was pretty scared. i said to myself, "is this how it ends?"
let me tell you, you develop religion pretty fast!
