I personally feel sleep paralysis is hallucinations. For me sleep paralysis happens right before I have an OBE. When I realize what is happening I immediately start praying if the hallucination is negative. That always solves my problems, then I just focus on leaving my body and having an OBE. Personally I feel we have nothing to fear but fear itself. If you believe in something and put your energy into it then you give it life. So, think happy thoughts.
