Dementia and drug use cause paranoia. That is very common. Some of other things that can include delusions and/or hallucination can be:
Narcolepsy
Hallucinogen use
Withdrawal from benzodiazepines
Some of those things on the list are very very rare cases but I just wanted to cover everything (or almost everything).
