Sometimes I play back my day if I'm having difficulty falling asleep. I watch myself as a omniscient narrator of the day. This always makes me fall asleep.

My near death experience came after waking up from surgery. I didn't really wake up and I remembered the nurses yelling at me and shaking me, but I was so peaceful just drifting off into a warm sleep, I didn't want to come back. I can say from what I experienced, it's definitely like going into a deep sleep.
