The psychotic does not merely think he sees four blue bivalves with floppy wings wandering up the wall; he does see them. An hallucination is not, strictly speaking, manufactured in the brain; it is received by the brain, like any 'real' sense datum, and the patient act in response to this to-him-very-real perception of reality in as logical a way as we do to our sense data. In any way to suppose he only 'thinks he sees it' is to misunderstand totally the experience of psychosis.

Probably she's the one who did it; I have no control of myself or anything that's happened. So now I'm waking up. I'm awake, he thought ... I've been destroyed and now that I'm awake all I can do is realize it ... The shock of getting up there and telling that account made me see. Mixture of lies and bits of truth. Woven together. Unable to see where each starts.
Philip K. DickI mean, after all, you have to consider we're only made out of dust. That's admittedly not much to go on and we shouldn't forget that. But even considering, I mean it's sort of a bad beginning, we're not doing too bad. So I personally have faith that even in this lousy situation we're faced with we can make it. You get me?
