BOO! The supernatural could frighten you and being held at gun point can do the same!
When students sought out a ghost they heard about, apparently, one teacher of theirs caught them and didn't appreciate that. He held the students at gun point for it, telling them to stay until the police came.
Maybe the ghost all along was just the teacher in the dark, dark night...Talk about a creepy teacher!
