Dementia and drug use cause paranoia. That is very common. Some of other things that can include delusions and/or hallucination can be:
Mental disorder
Fever
Speech by Governor Kugler on the economic outlook and monetary policy - Federal Reserve Board (.gov)
Migraines
Alzheimer's disease,
Charles Bonnet syndrome
