I am just curious--does this happen mostly at night? I had some really weird problems for years and was treated with all kinds of meds until I finally went to a sleep disorder center where they hook you up to all kinds of instruments and observe you while you sleep. The brain functions differently at night, it's complicated. I had undiagnosed sleep apnea as well as some sleep paralysis including hypnogogic hallucinations. There is even the disease narcolepsy. (A psychiatrist had already told me I had been hallucinating and tried to give me antipsychotic drugs.) Also, if you aren't sleeping normally, it can cause all kinds of neuro symptoms due to sleep deprivation. I have an unbalanced immune system and it aggravated already existing neurological problems. I don't know, it's just something to think about.
