What causes hallucinations?
Hallucinations are usually diagnosed alongside psychotic disorders, such as dementia, bi-polar disorder (manic depression), schizophrenia, substance abuse, as well as with some personality disorders. However, many famous people throughout history, including most of the great spiritual leaders, have heard voices or seen visions. And many people who have recently lost a loved one or who have gone through a traumatic experience, may also hear voices or see visions, if only for a short while.
