My dad has been seeing people that aren’t really there for the past two days, he swears up and down that they are really there even when I can’t promise him they aren’t, he says they are in his car in the house, on the roof etc, he also swears that there isn’t nothing wrong with him when obviously there is. He isn’t on drugs or anything like that, I’m really worried about him and need advice on what to do as he will not go to the hospital or a doctor.
