What kind of tricks have you done or seen in the haunted house?

The most outrageous thing was my friend. Once I went to a haunted house with him, and he actually took the initiative to pretend to be a ghost to scare me. He directly copied the ones from the staff who were pretending to be ghosts next to him. He stood up against the white wall, and then he started to show off his tricks, which scared me to death. After I came out, I naturally had to teach him a lesson.
