" But then I have long since grown accustomed to the thought that what we call dreams is semi-reality, the promise of reality, a foreglimpse and a whiff of it; that is they contain, in a very vague, diluted state, more genuine reality than our vaunted waking life which, in its turn, is semi-sleep, an evil drowsiness into which penetrate in grotesque disguise the sounds and sights of the real world, flowing beyond the periphery of the mind—as when you hear during sleep a dreadful insidious tale because a branch is scraping on the pane, or see yourself sinking into snow because your blanket is sliding off. "
