absolutely. to the schizophrenic the things they are hearing/seeing are absolutely real. if you hear someone call your name you're going to turn around and see who it was right? because you know in your mind you heard a real person call your name. it's the same with schizophrenia. the voices and people they see in their hallucinations are absolutely 100% real and it's a very bad idea to try and convince him/her otherwise.
are there situations where a schizophrenic can not differeniate between visual hallucinations and reality?
