Seems legit. Although it naturally begs another question, that being how do deaf and blind schizophrenics “hear” voices in their heads?
Tactile illusions of Braille? Finding messages in the gravel? Imaginary Scentmonsters? Good question . . . Of course, the advantage to this is, that if a human has no senses we won’t be able to diagnose him with schizophrenia anyway, so we’ll never find out.
