Miguel de Cervantes
Now blessings light on him that first invented this same sleep: it covers a man all over, thoughts and all, like a cloak; 'Tis meat for the hungry, drink for the thirsty, heat for the cold, and cold for the hot. 'Tis the current coin that purchases all the pleasures of the world cheap; and the balance that sets the king and the shepherd, the fool and the wise-man even. There is only one thing that I dislike in sleep; 'Tis that it resembles death; there's very little difference between a man in his first sleep, and a man in his last sleep.
