Answer 1

You know how you can tell where “you” end and “the world” begins? You can tell your arm and memories are part of “you” and somebody else’s arm, memories and a random table are “not you”? Ego death is when that stops being possible.

I’ve experienced it on high doses of shrooms and ketamine.
