Hi I would be very happy to help assist you in understanding your dream. First I have a few questions. Is this experience something you have had for a while, or is it a new experience you are just now receiving? May I ask if there is anything in your life that you feel would cause you to under go this strong presence you are feeling relating to your sleep and dreaming?
I am wondering if this relates to extra stress your body maybe feeling. Our bodies are all different, but every human's body will need to "relieve" any extra stress or worry in some manner. Perhaps your body goes into this sort of sleeping and dreaming state when it feels this extra pressure. May I ask, do you feel at all stressed right before this takes place?
Do you have any sort of idea of what causes your paralysis nightmare dreams?
Do you feel that this state of dreaming is causing you any harm? You mentioned the feeling of anxiety that comes with the sleep paralysis. Anxiety comes from extras stress on the body. Can be from anything going in on your life and even suppressed memories. Perhaps you have suppressed memories from your childhood that may be causing this. Do you have any thoughts regarding that?
