" The speed limited my vision to the tunnel of the Toyota's headlights. The body could drive, I told myself, while the mind maintained. Maintained and stayed away from the weird peripheral window dressing of amphetamine and exhaustion, the spectral, luminous vegetation that grows out of the corners of the mind's eye along late-night highways. But the mind had its own ideas, and Kihn's opinion of what I was already thinking of as my "sighting" rattled endlessly through my head in a tight, lopsided orbit. Semiotic ghosts. Fragments of the Mass Dream, whirling past in the wind of my passage. Somehow this feedback-loop aggravated the diet pill, and the speed-vegetation along the road began to assume the colors of infrared satellite images, glowing shreds blown apart in the Toyota's slipstream.
