A hallucination is a sensory perception experienced in the absence of an external stimulus, as distinct from an illusion, which is a misperception of an external stimulus. Hallucinations may involve one or more of the senses, including taste smell and touch. The most cornmon are hearing voices and visual. Hallucinations are less likely to occur when the person is occupied or interested in what is going on around them. A hallucination occurs when environmental or surroundings, emotional, or physical factors such as stress, medication, extreme fatigue, or mental illness cause the mechanism within the brain that helps to distinguish conscious perceptions from internal, memory-based perceptions to misfire. As a result, hallucinations occur during periods of consciousness. They can appear in the form of visions, voices or sounds, tactile feelings, smells, or tastes. Hallucinations can also occur in patients who are not mentally ill as a result of stress overload, hypertension or exhaustion, or may be intentionally induced through the use of drugs, meditation, or sensory deprivation. People may experience hallucinations as part of their normal developmental stages, especially during the preschool years, in the 2-5 year old range. In some cases, hallucinations, may be normal. For example, hearing the voice of, or briefly seeing, a loved one who has recently died can be a part of the grieving process. Hallucinations that are symptomatic of a mental illness such as schizophrenia should be treated by a psychologist or psychiatrist.
