Hello steelcurtain27: I'm so sorry you are having these awful nightmares! They sound simply horrible! Years ago, I used to experience episodes of sleep paralysis. They were terrifying. So I do know something about that.

For many years I didn't know anything about what sleep paralysis entails, which made the experiences all that much more disturbing. I would simply wake up & be unable to move or make any kind of sound whatsoever. I taught myself to simply focus my attention on the index finger of my right hand & keep trying to move it until I actually could move it. Once I could move just that one finger, then the paralysis would disappear.

I do also recall, a few years ago, when I was in the hospital following an overdose I had taken, I had some very vivid & disturbing dreams. (I'll spare you the details!) Fortunately, as my brain recovered from all of the med's I had taken, the dreams subsided. I hope you can find a way to resolve the ones you are having too.
