I don't get sleep paralysis falling asleep, I get it waking up. Waking in the middle of the night, or even an hour before my alarm. The first time it happened I thought I must have had a stroke, because I couldn't move. All I could do was move my eyes from side to side and blink.
It doesn't happen often, but it used to be scary. I don't hallucinate per se, but I do seem to dream (it sort of overlays reality). Its just a case of the brain waking or starting to wake before the body get the signal. Usually it just takes a little time to wake up OR sometimes I just close my eyes and go back to actually sleeping. I can do that as long as I don't freak out or try to breathe differently than the auto-pilot is already doing.
