The most popular hallucinations are visual and auditory. Visual hallucinations can range from simple disturbances like flashes of light to complex scenes, affecting the individual’s ability to differentiate between real and imagined stimuli. 2008;1:6.

We do not know for sure how abnormal visual perception might cause hallucinations, but there is a hypothesis that involves The visual hallucinations in Parkinson’s, for instance, are thought to stem from disruptions in dopamine pathways and degeneration in areas involved in visual processing. Some schizophrenic patients can experience tactile hallucinations, where the patient feels something that is not there. Similar hallucinations are also reported by approximately 20% of patients with schizophrenia. Most data concern auditory/verbal hallucinations. Schizophrenia and auditory hallucinations.
