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. DickGrief causes you to leave yourself. You step outside your narrow little pelt. And you can’t feel grief unless you’ve had love before it - grief is the final outcome of love, because it’s love lost. […] It’s the cycle of love completed: to love, to lose, to feel grief, to leave, and then to love again. Grief is the awareness that you will have to be alone, and there is nothing beyond that because being alone is the ultimate final destiny of each individual living creature. That’s what death is, the great loneliness.
