Visual hallucinations

Description

Hallucinations involving sight in the absence of an actual visual stimulus that are not restricted to the period of awakening or the onset of sleep. Visual hallucinations may involve formed images, such as of people, or of unformed images, such as flashes of light. Visual hallucinations must be distinguished from illusions, which are visual misperceptions of real external stimuli.
