Other causes include hearing loss and epileptic activity.

Reports have also mentioned that it is also possible to get musical hallucinations from listening to music for long periods of time. This should be distinguished from the commonly experienced phenomenon of earworms, memorable music that persists in one's mind. These hallucinations can be caused by: lesions on the brain stem (often resulting from a stroke), sleep disorders such as narcolepsy, tumors, encephalitis, or abscesses. In the latter, people will hear music playing in their mind, usually songs they are familiar with. Other types of auditory hallucinations include exploding head syndrome and musical ear syndrome. They may occur in mentally sound people and with no known cause. In these, people more often hear snippets of songs that they know, or the music they hear may be original. These three categories do not account for all types of auditory hallucinations. There are three main categories into which the hearing of talking voices often fall: a person hearing a voice speak one's thoughts, a person hearing one or more voices arguing, or a person hearing a voice narrating their own actions. However, individuals without any psychiatric disease whatsoever may hear voices, including those under the influence of mind-altering substances, such as cannabis, cocaine, amphetamines, and PCP.

This may be associated with psychotic disorders, most notably schizophrenia, and this phenomenon is often used to diagnose these conditions. While experiencing an auditory hallucination, the affected person would hear a sound or sounds which did not come from the natural environment.Ī common form of auditory hallucination involves hearing one or more voices without a speaker present, known as an auditory verbal hallucination. An auditory hallucination, or paracusia, is a form of hallucination that involves perceiving sounds without auditory stimulus.
