I love Halloween! It's the one time of year that I'm allowed to scare children. All the other times people get upset.
@RickiTarr many years ago, I helped out a charity-run haunted house. They got permission to use an out-of-business mall, setting up room after room going in and out of the old store spaces.
We had a nightmare on Elm Street room. Guests would walk in between two half walls, and see the first Freddy actor cone towards them, then round a corner where there was a second, and around an other, and there was a third.
The effect of Freddy jumping ahead like that really worked well.
