Omg captin... that powerrangers video... that brought back so many memories ... But it also made me laugh SO HARD.

But yeah that whole "life coma" idea, i've pondered that a lot... Another alternate of that could be, What if we weren't even really human? What if this whole expirience of a human life was what other life forms expirienced as ENTERTAINMENT?! Life forms that had no need for "time", they lived outside the time dimension, but for entertainment, used our human lives like a video. But for the sake of entertainment, allowed their memories (as far as we can comprehend memories, technically without time a being exists with infinity) to be erased... I usually visualize some strange creature exiting a cryogenic chamber, pulling out a tiny rectangle from some kind of watch, with a little inscripition "Human Life" on it.
Good stuff.
