How To Treat Nocturnal Hallucinations?

I have mostly nocturnal hallucinations, with eyes open or others with eyes closed. My eyelids occasionally stick and need to be pushed open with fingers; I bite the back of my tongue and my bottom lip which interferes with my speech - I m told I look like a fish when it happens. I also have charley horse-like cramps on both sides of my neck with/without movement. Neither psychiatrists nor neurologists seem to take my symptoms seriously. I m an 81 year old female who has lived and worked in Bangladesh, Pakistan, Ghana, Tanzania, Rwanda and England (during madcow outbreak). I m late for an appointment so I ll get back to you later.
