" The town was peopled with sleepwalkers, whose trance was broken only on the rare occasions when at night their wounds, to all appearance closed, suddenly reopened. Then, waking with a start, they would run their fingers over the wounds with a sort of absentminded curiosity, twisting their lips, and in a flash their grief blazed up again, and abruptly there rose before them the mournful visage of their love. In the morning they harked back to normal conditions, in other words, the plague. "

― Albert Camus , The Plague
