Hypnagogic hallucinations are part of a triad of symptoms that are narcolepsy related. A sleep neurologist ((specialist) may be able to help with the hallucinations. I just recently figured out my Restless leg syndrome was partially a side effect of wellbutrin which I had been on for years. I’m off the Wellbutrin and off the 6 tabs of carbidopa-levodopa a day I was on for RLS. It’s still present but I am managing it with tylenol and a heating pad. My cervical pain after fusion is much better now with a very flat travel size pillow and gel ice pack. It’s amazing how much we can help ourselves with research and self experimentation, trial and error measures!
