Summary:
    New research suggests that auditory hallucinations in schizophrenia may come from a brain glitch that confuses inner thoughts for external voices. Normally, the brain predicts the sound of its own inner speech and tones down its response. But in people hearing voices, brain activity ramps up instead, as if the voice belongs to someone else. The discovery could help scientists develop early warning signs for psychosis.

Auditory and even visual hallucinations are also a product of extreme sleep deprivation, whether the lack of rest is drug induced or otherwise.

Those go away with adequate rest in the latter case.
