Did i experience mania or hypomania or just plain weirdness?

you might have been having whats known as a waking dream....your mind and subconscious can literally play tricks on you, (maybe it was all the caffeine) so you feel as though you were up all night. have you ever seen the film the machinist? something might be playing on your mind. another explanation that some people believe is 'out of the body experience'. i really doubt that all what you experienced actually happened tho.
