I was back in disgust. I stood in the centre of the big room, naked, letting the heat strike me from the three points of heat, and I knew, and it was an illumination — one of those things one has always known, but never really understood before — that all sanity depends on this: that it should be a delight to feel the roughness of a carpet under smooth soles, a delight to feel heat strike the skin, a delight to stand upright, knowing the bones are moving easily under flesh. If this goes, then the conviction of life goes too. But I could feel none of this. The texture of the carpet was abhorrent to me, a dead processed thing; my body was a thin, meagre, spiky sort of vegetable, like an unsunned plant; and when I touched the hair on my head it was dead. I felt the floor bulge up under me. The walls were losing their density. I knew I was moving down into a new dimension, further away from sanity than I had ever been. I knew I had to get to the bed fast. I could not walk, so I let myself down on my hands and knees and crawled to the bed and lay on it, covering myself.
