Running commentary, voices discussing/commenting
Visual hallucinations
Elementary - flashes of light
Fully organised - visions of people, animals
Can be seen in organic states, eg delirium
More common in acute organic states with clouding of consciousness than in functional psychosis
Functional hallucination
Auditory stimulus causes a hallucination
Reflex hallucination
Stimulus in one sensory modality produces a sensory experience in another
