My pdoc at the hospital asked me: if the voice was inside my head---or heard outside, if the voice was me--or sounded like someone else, if there was one--or more than one, if they talked to me--or each other, when they did talk to me were they nice--or telling me to hurt myself or others. I don't know if that is more a personal panel of questions based on my answers...or a general battery of questions, sorry =/

Auditory hallucinations are at least fairly common in: schizo affective disorder, schizophrenia, ptsd, severe depression--I know of these, there maybe others.

I don't know your situation, but if you have a therapist or pdoc you may want to ask about it...or with your general practioner if you don't have either a t or pdoc.

Hope that helps?
