My Train Goes Through Everything

Someone blocked me in an alley. He can fold space into paper and ask me: "Where is the train?" I don't know. But there is a cane under the wall - black, in the shape of a locomotive. I picked it up and it never left me. Later I learned that there is a world below the world. From the abyss to the pond to the pool, there are layers of isolation. My cane is a train that passes through everything - every depth, every iron law. But every time I wear them, I forget something. What did you eat yesterday? Classmate's name. The way home. One day I will forget who I am. But I can't stop. Because this train is still moving forward.
