For example, sometimes you're sitting listening in class listening to professor lecture but your head is nodding and eventually you close your eyes and you're sleeping. But then you seem to catch yourself and jerk yourself awake. What causes that?

It's your brain telling you, "are you supposed to be sleeping?"
(a survival technique)
There was this guy in my chemistry class all the way up in the front row who fell asleep. His brain did not give him this jerking signal and he was bent over and on his way to the floor. The instructor stopped talking and looked at him while he slowly descended to the floor in front of him. Just before he hit the floor, the guy next to him grabbed his sholder and woke him up. The whole class laughed.

In Psychology class, I learned that this is called a Myoclonic Jerk. And according to Sylvia Browne, it happens when you've been "Astral Traveling" and you come back into your body and don't fit quite right at first. In other words, a bumpy landing.

i think it's because your muscles are relaxing as you're falling asleep.
sometimes, too, it's because you're having a dream about falling. lol That happens to me sometimes. I guess we just translate dream into reality?
