Hi again. Does anyone know if auditory hallucinations are a common symptom for a bi-polar disorder or is it more of an anxiety thing? Because almost every day I'll be home alone and think I hear my parents fighting below me. This always used to scare me as a child, I would usually curl up into a ball and play music really loud. But the problem is they haven't fought in years. They usually aren't home when this happens, and I have no close neighbors that I could have heard. Any suggestions?
