When preparing for Book One, I talked to a couple of psychiatrists about psychosomatic phenomena, neuroses and dissociative conditions, for example the so—called hysterical blindness suffered by many who saw the Killing Fields in Pol Pot’s Cambodia: their eyes objectively see, but they are not aware of it and are blind because they believe they can’t see. One specialist told me that among modern Western people, ’metaphorical’ symptoms such as Fredy or those Cambodians evince are much rarer now than earlier in the twentieth century or before. Nowadays most people are better equipped by education to verbalise their neuroses, and have lots of jargon in which to do so. For most of the dissociative dimension, I could draw on things I knew from within myself.
