I dreamed the city was built on a train schedule

I was walking through a city that didn’t exist yet—just grids of concrete and tracks, all laid out like a timetable. The buildings weren’t made of steel or glass, but of timetables themselves, folded and stacked. I heard the same train whistle over and over, not from a station, but from inside my own chest. When I tried to ask someone what time it was, they just pointed at the sky and said, 'It’s always on time.' Woke up with the hum of a diesel engine in my ears. Still don’t know if that’s a warning or a promise.
