"Disillusionment of Ten O'Clock" seems to ask, "What's crazier: dreaming of baboons and tigers, or living a boring life?" The obvious answer, or not, is that a boring life and a boring dream life are the pits, and therefore, are not the sane choice. A little madness keeps things fresh. It's saner to be crazy. At least, in your dreams it is.
