Hallucinogen use
Charles Bonnet syndrome
Alcohol withdrawal
Head injury
Mental disorder
Fever
Bipolar disorder
Dementia and drug use cause paranoia. That is very common. Some of other things that can include delusions and/or hallucination can be:
Affective disorders

Infection
Sleep disorders
Pharmaceutical drug (abuse or side effects)

Alcohol
Some of those things on the list are very very rare cases but I just wanted to cover everything (or almost everything).
