Phycosis-alcohol or...?

I meet a girl whose father seemed as strange person. When I told my mother something about him, she told me that is probably psychosis. I have noticed he is seeing, hearing, feeling, or otherwise perceiving things that are not there. I guess my mother’s right, but anyway, I would like to know that for sure. Is it possible alcohol do that to him, because I think she told me he used to drink a lot before?
