I can also "see" the room when I'm in sleep paralysis. I also make noises as I'm trying to cry out for help, but I hardly make a sound. I put tremendous effort into it. Seems like it goes on for at least half an hour (although I really have no idea) before I'm finally able to scream, or I wake up. And yes, I've also felt a "presence" in the room. No pressure though. It feels like an evil presence, and at these times I've even tried to make scary noises, or bark like a dog to scare the "presence" away. I am on Propanolol, and I've read where some people have nightmares with this drug, and it's true that I didn't have sleep paralysis until I started taking it. But I have no choice--I have to be on it for my mitral valve prolapse problems, which causes heart palpitations, and that is even scarier than sleep paralysis! So if drugs are causing it, it's kind of a darned if you do and darned it you don't situation. Also, I have found no connection to what I've eaten, and whether or not I have an episode. Wouldn't it be wonderful if they found a cure for this?
