Terror is the widening of perspective and perception. The horror was in knowing I was swimming down to a place most of us leave when we get out of diapers and into training pants. I could see it on Ollie’s face, too. When rationality begins to break down, the circuits of the human brain can overload. Axons grow bright and feverish. Hallucinations turn real: the quicksilver puddle at the point where perspective makes parallel lines seem to intersect is really there; the dead walk and talk; a rose begins to sing.
