Near death experiences sound like successful psychedelic experiences.. no need to believe anything in particular about them..
Whatever they are, I don't really trust them...there's something eerie and unrealistic, to me, of everyone, no matter what type of life they lived, or how they treated others, suddenly dieing and seeing a all loving ball of light with angelic entities waiting for them... Something just seems deceptive about that...and would make for a good book or movie...
