A psychiatrist is the best person to evaluate whether a person is hallucinating or it is a divine revelation. Therefore, if a person thinks they are experiencing such symptoms but are unsure if it is accurate, they should consult a psychiatrist. A psychiatrist analyses the frequency of the visions, whether the person is on prescribed drugs, and there is extreme stress. Doctors sometimes recommend brain scans to check whether a tumour is causing these delusions and hallucinations.
