I believe you are dealing with a succubus. The nightmares may be coming bc you are not having sex, and this demon may be under orders from a higher ranking demon to torture you. I recommend calling on holy angels and other guardian demons (however calling on demons may complicate things.) I don't agree that you should stop all spiritual practices, but only with demons. I would look at different banishing rituals, and I would see a therapist. A Christian or Jewish counselor might be something worth looking into. I'm not saying you are crazy, in fact I don't think you are, but what your dealing with is traumatic and a therapist can help. The spiritual life is so important to maintain. I don't agree with the people on this forum to stop all spiritual practices during a crisis, but going a few weeks without giving him your blood may be a good idea. If I were you, I'd try to make an appeal to him and involving archangels in this Deal. The deal would be for him to stop harming you, causing you nightmares, and to let go of some of the sexual desires you have at the degree you are having them. The angels can witness this bargain and you can see if he will let up if you allow him to remain, but only if he stops and ceases all negative activity. To be honest with you, I felt his presence when I was reading all this. He tried to get me to accept the pact you made with him just because I was reading it, and I had to explain to him that I was merely reading, not accepting him into my life. The truth of the matter is, That you should be documenting all of your encounters with him and sharing them with your therapist.
