“And so, as I sleep, some dream beguiles me, and suddenly I know I dream.Then I think: this is a dream, a pure diversion of my will; now that I have unlimited power, I am going to create a tiger.Oh incompetence! Never do my dreams engender the wild beast I longed for.The tiger indeed appears, but stuffed or flimsy, or with impure variations of shape, or of an implausible size, or all too fleeting, or with a touch of the dog or bird.”
