My most common auditory hallucination is what I call "chatter." Basically it's random nonsense speech, typically 3-5 word phrases, that happens in the background. I experience these whether I'm in a mood episode or not.

When manic I have two other kinds of hallucination. One is that when I try to read I hear someone else - usually the voice of a famous person - reading the text back to me at a slight delay. Makes reading impossible.

The other is hearing very loud whispers. Unlike all my other hallucinations, these are located outside my head.

What are your auditory hallucinations like?
