This is either the scariest ghostly sighting we’ve ever seen… or the most elaborate prank.
CCTV footage at an ancient high school in Cork, Ireland, has caught some pretty hectic paranormal activity going on in the halls (you can watch above).
The video begins with a door swinging open in the corridor of Deerpark CBS before a set of lockers starts rocking violently then spews out its contents. A wet floor sign is also knocked over like it has been kicked.
The footage was taken at 3am on a Sunday when nobody would have been in the school.
While some are calling the legitimacy of the video into question, Deerpark's Principal Aaron Wolfe says this isn't an isolated incident and there have been several spooky happenings in the school, which was founded in 1828.
He told Unilad News that the school's caretaker once stayed in the school overnight to protect some birds the school were hosting for an exotic bird show. However, he left the school in the middle of the night claiming he heard 'the last call' being played on the trumpet.
He also revealed: "The female members of staff do complain that this particular part is extremely cold. It’s also outside the Religion Room – which is weird."
Mr Wolfe added that a pupil complained of hearing crying in the bathroom.
What do you think? Has someone set up the ultimate prank or is it something more sinister...?
