Non-clinical Sleep and Wake-up Uses

Famous quotes containing the word sleep:
“A solitary traveller can sleep from state to state, from day to night, from day to day, in the long womb of its controlled interior. It is the cradle that never stops rocking after the lullaby is over. It is the biggest sleeping tablet in the world, and no one need ever swallow the pill, for it swallows them.”
—Lisa St. Aubin de Terán (b. 1953)
