Auditory Hallucinations. Theses auditory, or aural, hallucinations are the most common type of schizophrenia hallucination. They are a disruption of the normal hearing process, involving hearing annoyances such as clicks, hums, or screeches, and can be as complex as hearing complete voices.
This is the most common form of hallucination in schizophrenics and refers to the perception of non-existent sounds. In schizophrenia, patients often hear voices talking to them but the hallucinations may also take the form of whistling or hissing, for example.arious different forms of hallucination exist, with some involving voices that can be heard and others involving non-existent smells or tastes. Hallucinations are a common symptom of schizophrenia but they can also be caused by drug abuse or excessive alcohol intake, fever, bereavement, depression or dementia.
