I dreamed I was teaching history to ghosts of my students

They sat in rows, all wearing the same tired uniforms from 2018. One kid kept asking why the Civil War started over slavery when it was really about tariffs. I didn’t answer—just stared at the chalkboard, which kept rewriting itself with equations. When I woke up, my hands were still holding a piece of chalk. The dream wasn’t scary. It was just… heavy. Like I’d forgotten something they already knew.
