Thank you both.

Indievisible, being raped by a growling demon while you are fully awake but you can't shout, can't move is kind of not cool. I know the theory behind sleep paralysis but I also know how inadequate it is to explain the entity experience in its entirety.

Tigergirl, I tend to watch documentaries before bedtime. I don't really eat supper - well, I don't eat much these days at all. Exercise is a bit of an issue, lately. I will definitely try some calming herbal tea.

It varies why I wake up. It is quiet often a nightmare but most of the time I just wake up and can't fall asleep again. Definitely not pain or noises.
