What Happens When We Die?

Beautifulflaws describes a classic "out of body" (or OBE) experience after overdosing on sleeping medication whilst at college.

"I overdosed on sleeping meds my freshman year in college. I was legally dead for three minutes (or so I was told). I don't remember much, but when the EMTs came to my dorm I remember them asking me all sorts of questions to keep me awake and I just passed out, most likely mid-word. I do remember a little bit of the ambulance ride, but not from my own body. It was seriously the strangest thing I have ever experienced. It could have been a dream, but I saw my own unconscious body, completely flatlined, in the ambulance. I remember the EMT who was in the ambulance with me (whom I did not see before I passed out) had mint green hair and I couldn't remember his name, but I asked for him when I regained consciousness about three days later."

Similar experiences have been described by those that engage in physical exertion at high altitude, suggesting a link with oxygen deprivation. This causes a feeling of bilocation, during which a person feels as though they are observing the scene from multiple viewpoints at the same time.
