You need medical: help. If you aren't already working with a psychiatrist - that is critical Please get help now.

Narcolepsy: causes a phenomenon called sleep paralysis during which you cannot move and may see or hear things that no one else does. It is a very frightening experience and very difficult to snap out of. Often you will come out of it if touched. You nmay feel a need to cry out for help but be unable to make a sound. Tell your doctor about this and arrange to have a sleep study in consultation with a sleep specialist

Psychiatrist: I'm concerned about your symptoms and feel that a psychiatrist would be best qualified to evaluate and advise you about treatment. You need help as soon as possible as well as proper follow-up.

Insomnia might be due to several different reasons. First have a complete physical exam by a Dr. to rule out underlying biological problem. If no problem consult with a Clinical Psychologist for psychotherapy help & a Psychiatrist for medication. You need a sleep study.
