I don't get hallucinations from BP, but I had them before from Klonopin withdrawal and it freaked me out..... I was hearing 50's music (I don't even like 50's music) and my sisters voice was the DJ. I'm sorry you're dealing with this, I would call Pdoc tomorrow if it's still happening, maybe they can temporarily raise antipsychotic (or give you a antipsychotic?) until it goes away.
