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’s empty, the next it’s packed with people who all looked at me like I’d forgotten something. No train came. Just this endless signal light blinking green, and my hands full of tickets I couldn’t read. When I finally turned around, the tracks were gone, replaced by a long hallway lined with old mixing consoles. One of them was playing a song I’ve never heard but somehow know by heart. I woke up with my shoulders tight, like I’d been holding a weight that wasn’t there.
