Ah, sounds like sleep paralysis at it's nastiest. The best way to cure this is to stop fearing sleep paralysis all together. And if you don't fear it, try to make it fun. I know this sounds completely crazy, you're probablly thinking "How am I supposed to enjoy it when all this crazy stuff is happening?".

Well, SP can be quite crazy, and the manifestations and stuff you get out of it directly rely on your sub-conscious. So, if you begin to want to enjoy SP, you may find that it won't be as bad.
