Bipolar Disorder Support Group
Bipolar disorder is not just a single disorder, but a category of mood disorders marked by periods of abnormally high energy and euphoria, often accompanied by bouts of clinical depression. This is the place to talk about your experience with bipolar disorder, learn from others' experiences, and find support.

Hearing voices is psychosis .. I heard voices coming from my bushes once and was really paranoid...If you heard a voice coming from under your bed you'd know you weren't talking to yourself...x
I also hear voices, whispers behind my ear and in my head. They are distinctly different from my voice and say rotten things most of the time. Knowing it is NOT my voice confirms that's psychosis and Abilify helps but it doesn't wipe out the whispers all the way.
I talk to myself sometimes, quite similar to what Spacekat described. And then I have heard reiterated thoughts from things I've heard from other people in the past...like memories resurfacing.
But the voices of psychosis? Startling. At least in my experience.
