The dream would follow the same pattern all summer. I’d be seated on the train to work, riding the westbound route of the Northern Line. It was my normal morning trip, though the carriage seemed a little emptier than normal, and the scarf wrapped up over my chin meant it must have been winter above ground. In my stare: my foot, shaking, with both of my legs crossed as inconsiderately as usual. On my right: a man holding the Metro, but I could only see the front page, a blind spot for the brain, with its photograph and headline as indistinct as the reader’s face.
