lol....oxygen depletion? you'd have to have been holding your breathe since you took the hit, and went home...you were still breathing weren't you?...

you probably just had to hard a come up from smoking too much too fast, it will drain your blood sugar level, and it makes you look pale, feel tired/slow motion, and gives you a body high.

were you smoking sheesha out of the hooka though? because that's most likely it.
