Why do our deceased do not protect us from other bad spirits?
Dementia and drug use cause paranoia. That is very common. Some of other things that can include delusions and/or hallucination can be:
Dementia with Lewy bodies
Migraines
Infection
Hallucinogen use
Alcohol
Some of those things on the list are very very rare cases but I just wanted to cover everything (or almost everything).
Affective disorders
Charles Bonnet syndrome
