[slasherman]

I dont remember alot, but I know there was a teacher who always got completly ridiculed in class by his students. In one part he's at home, and hears the kids chanting in his head. They may have been chanting his name. For some reason I think it was on/around Halloween

..class of 1984

This may have been a different film, but I also remember one of the kids in his class cheating on a test and feeling giulty. He looked up and saw a dark ghost/witch thing at the classroom door
