“I often dream about falling. Such dreams are commonplace to the ambitious or those who climb mountains. Lately I dreamed I was clutching at the face of a rock but it would not hold. Gravel gave way. I grasped for a shrub, but it pulled loose, and in cold terror 1 fell into the abyss. Suddenly I realized that my fall was relative; there was no bottom and no end. A feeling of pleasure overcame me. I realized that what I embody, the principle of life, cannot be destroyed. It is written into the cosmic code, the order of the universe. As I continued to fall in the dark void, embraced by the vault of the heavens, I sang to the beauty of the stars and made my peace with the darkness.”

The Inferno (1917), Ch. XVI
Context: I went out on the street like an exile, I who am an everyday man, who resemble everybody else so much, too much. I went through the streets and crossed the squares with my eyes fixed upon things without seeing them. I was walking, but I seemed to be falling from dream to dream, from desire to desire. A door ajar, an open window gave me a pang. A woman passing by grazed against me, a woman who told me nothing of what she might have told me. I dreamed of her tragedy and of mine. She entered a house, she disappeared, she was dead.
