C.S. Lewis quote

This quote corroborates something that I saw in a dream once. Not gonna go into the whole thing, but read this and think about it:

"'Did they see Napolean?' 'That's right. They went up and looked through one of the windows. Napoleon was there all right.' 'What was he doing?' 'Walking up and down - up and down all the time - left-right, left-right - never stopping for a moment. The two chaps watched him for about a year and he never rested. And muttering to himself all the time. "It was Soult's fault. It was Ney's fault. It was Josephine's fault. It was the fault of the Russians. It was the fault of the English." Like that all the time. Never stopped for a moment. A little, fat man and he looked kind of tired. But he didn't seem able to stop it.'"
