Ceux qui revent eveilles ont conscience de 1000 choses qui echapent a ceux qui ne revent qu'endormis. The one who has day dream are aware of 1000 things that the one who dreams only when he sleeps will never understand. (it sounds better in french, I do what I can with my translation...)
I've watched you now a full half-hour; Self-poised upon that yellow flower And, little Butterfly! Indeed I know not if you sleep or feed. How motionless! - not frozen seas More motionless! and then What joy awaits you, when the breeze Hath found you out among the trees, And calls you forth again!
Sleep, thou repose of all things; sleep, thou gentlest of the deities; thou peace of the mind, from which care flies; who doest soothe the hearts of men wearied with the toils of the day, and refittest them for labor.
If you are with the quality, or at a funeral, or trying to go to sleep when you ain't sleepy - if you are anywheres where it won't do for you to scratch, why you will itch all over in upwards of a thousand places.
Indeed, sir, he that sleeps feels not the toothache; but a man that were to sleep your sleep, and a hangman to help him to bed, I think he would change places with his officer; for look you, sir, you know not which way you shall go.
