There is always a lot of strange things that happen in High Schools but this just may take the cake.
A security camera at a school in Ireland filmed several strange events that have people thinking a ghost is on the loose. A door opens and closes, a stack of lockers rock back and forth, a single locker flies open . . . and a folding "caution" sign suddenly collapses.
The school principal claims it's legit.
Prank or poltergeist? CCTV footage from Deerpark CBS, the oldest (and most haunted!!!!?) school on the south side of Cork City.
