Auditory hallucinations are among the most common. You might hear someone speaking to you or telling you to do certain things. The voice may be angry, neutral, or warm. Other examples of this type of hallucination include hearing sounds, like someone walking in the attic, or repeated clicking or tapping noises. Mental illnesses are among the most common causes of hallucinations. Schizophrenia, dementia, and delirium are a few examples. Substance abuse is another fairly common cause. Some people see or hear things that aren’t there after drinking too much alcohol or taking drugs like cocaine or PCP. 1 Residual schizophrenia -- a person is no longer experiencing delusions or hallucinations, but has no motivation or interest in life. 2  Schizoaffective disorder --a person has symptoms of both schizophrenia and a major mood disorder such as depression. Positive symptoms are disturbances that are “added” to the person’s personality. 1  Delusions -- false ideas--individuals may believe that someone is spying on him or her, or that they are someone famous. 2  Hallucinations –seeing, feeling, tasting, hearing or smelling something that doesn’t really exist. 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. Various 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. Visual hallucinations. Schizophrenics can also have visual hallucinations, which are the second most common type with this disorder. Visual hallucinations involve seeing things which aren’t really there. They may involve images which are very clear, as well as vague or distorted. Other types of hallucinations are olfactory, tactile and gustatory. 1  Olfactory hallucinations involve the sense of smell. 2  Tactile hallucinations involve the sense of touch, and may, for example, involve the feeling that snakes or bugs are crawling on or inside the body. 3  Gustatory hallucinations involve the sense of taste.
