Rhonnie and Sammi, thanx for your replies. I think there might be two reasons for our sleeping habits, weather we slept/sleep a lot (like you rhonnie, I sleep a lot too, 10 hours a day is about an average for me) or we tend to switch the days for nights. The long sleep might be cause we're just simply mentaly exhausted (I feel so at least), and the switching thing...just simply liking night more than day cause we don't have to face all our "problems", work, school and other stuff we have to deal with at days.
Anyway, there's this girl I know that had some psychological problems. She just couldn't trust anyone or was agraid to trust ppl, so her therapist told her that one day (tuesday lets say) from 6-8 pm she'll have to trust anything that anyone said. She went home after having a meeting with her therapist, and guess what happened...When that time(when she had to trust everything) came, she just fall asleep, not intentionally though. She remembered her "homework" only after she got up. And when she told her therapist about it, he said he thought that that would happen. It's a funny thing our head :p
Take care
