No. I used to fall asleep in class alot, when I'd wake up I would be able to see and hear but not move, it's a very scary experience.
A short amount of time which seems like an eternity, usually anywhere from 10-20 seconds. I may have had hallucinations but just not remembered it.
It may have lasted longer than 10-20 seconds for me, it's not something that I'd be able to remember easily, as it's just like dreaming, but I can't picture myself sleeping in class for too long
Oh, if it only lasts about 10 - 20 seconds that I may have had it before and not noticed it too much, although I don't ever recall having hallucinations.
Oh well, I'm going to bed... let's just hope a wild Pikachu doesn't appear and uses sleep powder then thunder wave. That would be gay.
