She used to say to him, If people knew what I was thinking they would put me away forever. But they would put us all away, he said. They have put us away. We are put away for our thoughts, one way or another. We have put ourselves away, he said.
— Don DeLillo, Mao II
Everyone carries a room about inside him. This fact can even be proved by means of the sense of hearing. If someone walks fast and one pricks up one's ears and listens, say in the night, when everything round about is quiet, one hears, for instance, the rattling of a mirror not quite firmly fastened to the wall.
– Kafka
