I'm sorry to hear about your bad dreams. I've also had my fair share of demonic dreams, pretty hideous ones, as well as being completely paralised in a half asleep/half awake state since I was a kid. If I ever find myself unable to call out to Jesus, I do it in my head, like a prayer in my dream, and He always helps me out. Of course I'll pray for you too.
Also, this may or may not help you: Recently after a certain bad dream I recognised the hideous creature in it to be identical to the image on the front of a Motor Head cd that was left in my room. I was shocked, but it made a lot of sense, as demons have a right to cling to certain unGodly objects. Maybe you should check your room for things like that?
