There are only two... «Frogs into Princes: Neuro Linguistic Programming»

There are only two distinctions between anybody in this room and an institutionalized schizophrenic: (1) whether you have a good reality strategy and you can make that distinction, and (2) whether the content of your hallucination is socially acceptable or not. Because you all hallucinate. You all hallucinate that somebody's in a good mood or a bad mood, for example. Sometimes it really is an accurate representation of what you are getting from the outside, but sometimes it's a response to your own internal state.

When we trained residents in mental hospitals we used to go up early and spend time in the wards because the patients there had problems we never had the opportunity to encounter before. We would give them the task of determining for themselves which parts of their experience were validated by other people, and which were not. For instance, with the cup-of-blood guy, we immediately joined his reality. "Yeah, warm this one up for me, will you?" We joined his reality so much that he came to trust us. And then we gave him the task of discovering which parts of his reality other people in the ward could validate for him. We didn't say this was really here and that wasn't, but simply asked him to determine which parts of his reality other people could share. And then he learned—as most of us have as children—to talk about those parts of reality which are either socially acceptable hallucinations, or that other people are willing to see and hear and feel, too. That's all he needed to get out of the hospital. He's doing fine. He still drinks cups of blood, but he does it by himself. Most psychotics just don't have a way of making distinctions between what's shared reality and what's not.
