I suggest you face this by simply shutting your eyes, sleeping, and just allowing whatever will happen to happen. Although it may be a bit scary but you will feel much better afterwords. I've never experienced anything anywhere near this level of lasting torment. However, I certainly have gotten really paranoid about nonsensical things that would just sound completely nuts and on one occasion even had the full alien abduction experience, they came in my room and stuck a needle into me, telepathically communicated and all that stuff. Thing is, I never really was abducted and none of the stuff I was paranoid about was actually real but simply facing the paranoid fears gave me peace of mind.
