How would a professor prevent students from being able to use a service like yours?

A lot of the time as I'm falling asleep my body jerks. Its pretty pronounced and obvious to my partner. Typically I don't wake up, but every now and then I've experienced this as a dream of falling and I've jerked awake. When this happens this very shortly after falling asleep. Why does this happen? Is it anything significant or does it happen to lots of people?

I seem to wake up at the drop of a pin. I sleep with a fan on and the same classical music CD every night because the predictable nature of it lets me tune it out and it masks sudden sounds. Why is it that I wake up if the dogs collar jingles two rooms away? My brain seems to be way more alert to sounds than anyone else I know. I've been this way since adolescence. I've never had kids (I know that can make some people more alert to sounds while sleeping)
