Of course you all know what flying feels like, because everyone has dreamed about flying, and it seems so beautifully easy - only, you can never remember how you did it; and as a rule you have to do it without wings, in your dreams, which is more clever and uncommon, but not so easy to remember the rule for.

你们当然都知道飞翔是什么感觉，因为人人都梦见过飞翔，而且觉得那样轻盈容易；只是你永远记不住自己是怎么做到的。通常，在梦里你还不用翅膀就能飞，这更高明、更奇妙，却也更难记住诀窍。
