A hallucinatory trance state of autohypnosis induced by long looks down into the swirling void mists off the edges of Plateau. A group of religious clairvoyants living on Plateau trace visions of Mist Monsters who live in the poisonous lower depths of the planet's surface. Teela Brown was caught in a Plateau trance by the hypnotic appearance of the Ringworld's mock-horizon, where land and sky meet at infinity. Also called highway hypnosis. Also called the far look.
