Many: Real psychosis? As in having hallucinations or delusions? Possibilities include schizophrenia, mania, drug abuse (especially stimulants), a variety of medical issues including brain tumor or trauma, metabolic abnormality, certain infections... the list is long. If the person can be reasoned with, suggest that they see a doctor. If not, you may need to call the police for your safety.
