I dreamed I was a train conductor with no train

I was standing on a platform that kept shifting like a tape loop — one second it was station B, the next it was a field of dead wires. No train came. Just me, a whistle I couldn’t blow, and a schedule written in a language I used to know but forgot. The passengers were all dogs. They didn’t look at me. They just sat there, shoulders slumped, reading my mood from my posture. I woke up with my neck stiff, like I’d been holding a weight for hours. Still don’t know if I was the conductor or the thing being carried.
