There open up, deep inside a city, reflected streets, streets which are double, make-believe streets. One's imagination, bewitched and misled, creates illusory maps of the apparently familiar districts, maps in which the streets have their proper places and usual names but are provided with new and fictitious configurations by the inexhaustible inventiveness of the night.
So now I lye by Day and toss or rave by Night, since the ratling and perpetual Hum of the Town deny me rest: just as Madness and Phrensy are the vapours which rise from the lower Faculties, so the Chaos of the Streets reaches up even to the very Closet here and I am whirl'd about by cries of Knives to Grind and Here are your Mouse-Traps. I was last night about to enter the Shaddowe of Rest when a Watch-man, half-drunken, thumps at the Door with his Past Three-a-clock and his Rainy Wet Morning. And when at length I slipp'd into Sleep I had no sooner forgot my present Distemper than I was plunged into a worse: I dreamd my self to be lying in a small place under ground, like unto a Grave, and my Body was all broken while others sung. And there was a Face that did so terrifie me that I had like to have expired in my Dream. Well, I will say no more.
