Edith Wharton,
Twilight Sleep
(1927)
“ Lita was on the lounge, one long arm drooping, the other folded behind her in the immemorial attitude of sleeping beauty. Sleep lay on her lightly, as it does on those who summon it at will. It was her habitual escape from the boredom between thrills, and in such intervals of existence as she was now traversing she plunged back into it after every bout of outdoor activity. Nona tiptoed forward and looked down on her. Who said that sleep revealed people's true natures? It only made them the more enigmatic by the added veil of its own mystery. ”
