Auditory hallucination
There are three main ways in which the hallucination may form: a person hearing a voice speak thoughts, a person hearing one or more voices arguing, or a person hearing a voice narrating their own actions. There can be other types of auditory hallucinations besides these three. These include hearing music playing inside the mind, usually songs that the person is familiar with. This is usually caused by damage to the brain, hearing loss or epileptic activity.
