Is it considered an auditory hallucination if one hears something with a stimulus? there was always a real voice from people but i misconstrued it.

Doubt that is an: Auditory hallucination. An auditory hallucination is hearing voices or sounds that aren't there.

Misperception: What you describe would be a misperception or illusion, since there is an outside stimulus. As dr. Fowler says, hallucinations are perceptions that come without an outside stimulus at all. Both illusions and hallucinations can be problematic for the person experiencing them, though.

Illusions: are misconceptions of actual stimuli, whereas the definition of an hallucination is an experience involving the apparent perception of something not present. In other words, hallucinations occur in the absence of any outside stimuli (i.e. outside of a person's brain).
