Hallucination simulation

I just had a walk through of the virtual hallucinations exhibit in Second Life. I have no previous exposure to schizophrenia via relatives or clinical cases (dogs don't tell me what they're seeing and hearing, although we do have dogs that act in inexplicably aggressive ways, so who knows?). I had been aware that people with schizophrenia can have hallucinations. What surprised me was the content of the hallucinations - there was a lot of emphasis on death and self-hatred. What I found most interesting was that there wasn't anything particularly strange about the content of the messages (you are worthless, you don't deserve resources, you should kill yourself to stop contaminating the world). Anyone who has been suicidal will tell you that these messages are very very typical; the only difference between a suicidal person's perception and what I gathered from the simulation is that a suicidal person hears these messages in their head and understands that it is their own brain or inner voice saying those things, whereas for a person with schizophrenia it appears to be coming from an external source. So who is less sane? A suicidal who argues with themselves, or a schizophrenic who argues with an imaginary outsider?
