It was in this man's class that I first began to wonder if people who wrote fiction were not suffering from some kind of disorder--from what I've since come to think of, remembering the wild nocturnal rocking of Albert Vetch, as the midnight disease. The midnight disease is a kind of emotional insomnia; at every conscious moment its victim--even if he or she writes at dawn, or in the middle of the afternoon--feels like a person lying in a sweltering bedroom, with the window thrown open, looking up at a sky filled with stars and airplanes, listening to the narrative of a rattling blind, an ambulance, a fly trapped in a Coke bottle, while all around him the neighbors soundly sleep. this is in my opinion why writers--like insomniacs--are so accident-prone, so obsessed with the calculus of bad luck and missed opportunities, so liable to rumination and a concomitant inability to let go of a subject, even when urged repeatedly to do so.
