If sleep is truce, as it is sometimes said, a pure time for the mind to rest and heal, why, when they suddenly wake you, do you feel that they have stolen everything you had? Why is it so sad to be awake at dawn? It strips us of a gift so strange, so deep, it can be remembered only in half-sleep, moments of drowsiness that gild and adorn. The waking mind with dreams, which may well be but broken images of the night’s treasure, a timeless world that has no name or measure and breaks up in the mirrors of the day. Who will you be tonight, in the dark thrall of sleep, when you have slipped across its wall? Jorge Luis Borges
