Kurt Vonnegut, Slaughterhouse Five:
Billy now shuffled down his upstairs hallway, knowing he was about to be kidnapped by a flying saucer. The hallway was zebra-striped with darkness and moonlight. The moonlight came into the hallway through doorways of the empty rooms of Billy’s two children, children no more. They were gone forever. Billy was guided by dread and the lack of dread. Dread told him when to stop. Lack of it told him when to move again. He stopped.
