I've always hated NDE. It's a natural phenomenon that's often used as a con game by half-assed tv "psychics" to bilk the easily fooled.
I don't know if it was a NDE but I had an alergic reaction and passed out, I found myself floating near the ceiling, able to see and hear everyone in the room, including myself, while people around me were trying to revive me.
(I noticed that everyone else was better dressed and that I needed new shoes)
