According to his recent biographer, Kenneth S. Lynn, Hemingway sometimes bragged that his chronic insomnia was the result of horrific battlefield memories; but evidence shows that he suffered the malady even in childhood.
A 1927 short story, “Now I Lay Me,” convincingly relates his alter-ego Nick Adams’ lifelong insomnia to a fearful distrust of himself and the world. The story takes place in soldiers’ quarters near the battle lines, where Nick lies sleepless late at night.
海明威1927年写的的短篇小说“Now I Lay Me”里面就写到了堪称作者第二自我的尼克·亚当，尼克一生都饱受失眠折磨，原因是对自己和世界的极度不信任。小说里的故事发生在战争前线的兵营里，尼克半夜睡不着，就干躺着。
Tormented by the incessant chewing of silk-worms in the brush outside (the worms suggesting both death and a mindless, ongoing nature), Nick confesses that “I myself did not want to sleep because I had been living for a long time with the knowledge that if I ever shut my eyes in the dark and let myself go, my soul would go out of my body.”
