Both are caused by certain mental illnesses but can also be triggered by medical conditions, injuries, or by no known cause at all. A hallucination involves the senses and feels real but is not. A delusion is a false belief that persists in spite of evidence. Neither is always cause for concern, but when experienced should lead to medical and mental health evaluations. Delusions and hallucinations are similar but also have some significant differences.
