I dreamed I was a train that never arrived

I was a freight train, steel and steam, rolling through a valley so wide it felt like the world had forgotten how to end. No passengers, no signal lights—just the rhythm of wheels on rails and the silence between stations. I kept thinking: if I don’t stop, where do I go? But the tracks didn’t lead anywhere. Just forward. And then I woke up with salt on my lips, like I’d been sailing through fog, not iron.
