Hallucinations and Delusions are both symptoms of schizophrenia, which is a sure indication of a misplaced perception of what reality is. Although both words are used to mean the same thing, they differ in meaning and in processes that lead to their occurrence Hallucinations occur as a result of fatigue, stress, drugs, or mental weaknesses, which causes the brain to remember some thoughts and perceptions already stored. Therefore hallucinations occur at conscious periods.
Delusion, on the other hand, is a usual display of multiple personalities at the same time, which causes swings in behavior and disorders. It also means a strong conviction in the unimaginable or impossible regardless of real proofs that disapprove those conceived imaginations of the Unreal and impossible. Both hallucinations and delusions are an end result of deep stress, depression, and severe anxiety. There are medications used in tackling hallucination when it has stayed for on a long term basis.
