I sleep randomly, between maybe 3 and 24 hours at a time. I'm awake between maybe 16 and 24 hours at a time. When I sleep a long time (which is usually), I often frequently wake up for a minute and then fall back asleep, usually changing my position when I do that. I guess I'm usually a light sleeper. Just open my door and I wake up. Probably because I sleep way more than is necessary. Every second I'm asleep, I'm dreaming.
