strange sleeping habits

I have the absolute weirdest sleeping habits of anyone I know. I can be asleep for an hour or 12 hours and be completely fine. Two nights ago, I fell asleep at 4am and woke up at 5am... the night before last I fell asleep at around 2 or 3am and woke up at 730am and last night I fell asleep at 8pm and have been awake since 2am... what the heck? Oh well, I'll take this time to edit pictures and look over schoolwork I guess... I might end up just trying to figure out how to set up a .com instead though.
