I usually sit on the computer at night until I'm screwed cause I've always had problems with sleeping and I hate thinking in bed `cause I sit there for ages, it's easier to just pass out.
Other than that I roll around alot too, changes all the time.
I typically fall asleep on my stomach, however I roll around...alot. I have also slept walked, and talk in my sleep alot. From what my family has told me, I will apparently carry on meaningful conversations with my eyes open and blinking...though I never remember them the next day
I also dream, vivid weird dreams every night. Somtimes I also dream of new inventions or how to make something run better, but I always wake up before I see how I built them
