I suffer from confusional arousals during sleep with occasional hallucinations. sleep study was normal. what can i do to fix this?

Consider an analogy:: Your car engine knocks and misses at certain speeds. Your mechanic can't find anything wrong. What can you do to fix this? How can you "fix this" if you don't know what's broken? Options: 1) Get another test. 2) Get another mechanic. 3) Get another car. Option #3 doesn't apply in medicine; so you need to get another test or get another opinion. No "fixing" till you know what needs fixing.
