Dementia and drug use cause paranoia. That is very common. Some of other things that can include delusions and/or hallucination can be:
Infection
Affective disorders
Have you ever secretly watched someone while they were doing something private?
Withdrawal from benzodiazepines
Brain Tumors
Migraines

Alcohol withdrawal
Dementia with Lewy bodies
Alcohol
Parkinson's disease
Pharmaceutical drug (abuse or side effects)
Fever
Bipolar disorder
Grief (yes, sadly)
Delirium tremens
Some of those things on the list are very very rare cases but I just wanted to cover everything (or almost everything).
