I dreamed I was grading papers in a train station that kept changing eras

The kids turned in essays about the Treaty of Versailles, but every time I picked up a stack the station flickered — wood benches became plastic, the clock went from Roman numerals to digital. I couldn't find the right platform, and the kids kept asking me what century we were in, like it was my job to decide. Woke up feeling like I'd actually taught a double period.
