After Harry Potter came out, many videos surfaced online of people running into brick walls at train stations as a joke. While at one of these such train stations a friend dares you to run into a wall. They pull out their phone and start recording as you reluctantly run towards the wall. Expecting to hit it, you brace for impact but none comes— when you open your eyes again, the platform is empty and the train you see is most definitely not the Hogwarts Express.
