Happens to me fairly frequently. Stress is definitely a factor. Sometimes I'll wake up, be unable to move, have all kinds of horrifying auditory hallucinations, fall back to sleep, wake up again, be unable to move....etc. This will happen for 2-3 cycles.

Maybe happens once every 2 months or so.

I've found I can control my eyes and my rate of respiration. I've found that if I start breathing really loudly it'll wake up my wife, who then shakes me awake. As soon as I get some sensory input from her moving me I snap out of it.

Very freaky. Fortunately I read about this some time ago and found that it's basically nothing to be concerned about. Though it's scary as hell when it happens to you!
