Dream Detail

my dream about a train. Recently, I’ve had several dreams about trains, and here’s the latest one: I’m on an old sleeper compartment coach, like from my childhood—it’s old, but cozy, with soft beds and pillows. We arrive at the final station, in the terminal of some city. But I don’t get off; instead, I decide that I need to go back three stations to reach my destination. A passenger enters the compartment to head back the other way—a man—and he says he needs a safe. I’m surprised there’s a safe on the train, so I look at the wall, and there really is a "safe," only it looks like three old postal boxes—twisted metal and not very secure. Please help me interpret this dream
