these kinds of hallucinations are normal for scizophrenia. My son sometimes thinks his dead father is talking to him. at one point he hid our apparment keys in a hole in the ground in some ivy type bushes and after 2 hours of the two of us thrashing through the bushes trying to locate the keys that he told me had dropped he sat down and told me his dead father told him to hide my keys so that we could not move into a different appartment. After that from time to time he would be talking in his room and I would listen and hear him say - What dad I can't hear you very good. When I told his therapist she said he may be idolizing his father because he didn't have a chance to say goodbye. So my son and his therapist heald a mock funeral in therapy complete with his therapist reading parts of his fathers letters that I saved for my son to have when he is an adult. After that every time I caught my son talking to his dad he was telling him - you're dead, I'm alive. leave me alone. I have been pretty much told my son has schizophrenia but this state does not recognize that in children so he won't recieve that label until he is 18, and at this moment he is on medication - Resperitol and is not having any audio or visual hallucinations.
