Grief (yes, sadly)
Sleep disorders
Do you need goggles for red light therapy?
Brain Tumors
Dementia with Lewy bodies
Mental disorder
Did you become a cuckold for your wife?

Dementia and drug use cause paranoia. That is very common. Some of other things that can include delusions and/or hallucination can be:
Withdrawal from benzodiazepines
