I was walking through school and it was snowing in school. I didn't know where to go for revision so I just sat down on this table. My crush Alan sat next to me and swapped with the girl who sat opposite me. We talked about how he could write in h8s revision guide but I couldn't, then this guy came and slid on a non-existent pavement that was covered in snow. This guy then came and said he was trying to remove the snow. We tried guessing his age and it turned out he was 18. The man then walked across the stone into a non-existent house and disappeared. The last scene was a guy kidnapping a boy who looked like Harry Potter.
