The study of Australian scientists has shown that hallucinations are not always associated with some serious mental disorder. For once in their life every twentieth man has heard voices or seen things that did not exist in reality, being awake and not being under the influence of drugs or alcohol at that very moment.

Scientists analyzed information obtained from 31000 people from 18 countries who were interviewed during the big survey dealing with the mental health of the Earth population.

What are hallucinations mental health EVERY TWENTIETH INHABITANT OF THE PLANET HAS EXPERIENCED HALLUCINATIONS What Are Hallucinations

People, who presumably have had any of psychotic disorders, e.g. schizophrenia or manic-depressive psychosis, did not take part in the survey.

Traditionally people believe that hallucinations are a symptom of a mental illness, however, the study conducted shows that even sane people have had such an experience. About 6% of the respondents admitted that they experienced such feelings at least once in their life. Some people reported that they hallucinated only once, whereas other people said that it had happened several times. What is interesting is that there were more women than men who reported about  their hallucinations.
