I took some photographs in a dream. I took so many that I filled a 36-exposure roll of film. I took them to the developer's. They could develop them in 24 hours, 48 hours, or 3 days. I was quite excited about the photographs, so I decided to go for the 24 hour service. When I got the photographs back I was disappointed, because they were all blank, just white rectangles. I thought that perhaps, if I stared at them for long enough, I might find myself back in the dream. I tried this for a while, sitting on a wet bench on a drizzly day in Regent's Park. It didn't work. A mother walked past with her child, who said, "the sky's not grey." But it was.
