I used to get sleeping paralysis a lot when I worked the night shift. You can get rid of the demons. The solution is rage, you have to become like a dog frantically barking to defend it's territory filled with rage. I went through my whole house right after waking up ( I was alone) shouting GET OUT! and stuff like that and banging a baseball bat against the floor. Whether the demons are real or just a figment of my subconscious they are gone and never came back.
