You have enough on your plate to worry about while working your way through school, right? Homework, pop quizzes, and (especially) gym class all have anxiety-inducing factors. But students attending Deerpark CBS in Cork, Ireland also have to be wary of a ghost wandering their halls on top of all the standard school stressors.

And judging by the CCTV footage, this ghost is pissed off.

On October 1st at 3 a.m. — “the witching hour” oddly enough — the Deerpark security cameras caught something quite eerie, to say the least. In a deserted corridor, something amazing yet terrifying went down and we’re all grasping for an explanation.

The door slams, a locker unit rocks back and forth, and some poor kid’s locker was ransacked. As amateur ghost hunters, we’d say this is poltergeist activity at its finest.

Some critics in the video’s comments write that it must be a prank. The evidence is too good to be true. But Deerpark’s principal, Aaron Wolfe, denies any such claim.

"If it's a prank we don't know how it was done. Motion sensors were set off at this time, that's how it was caught," Wolfe told UNILAD.

Wolfe continued to explain that this isn’t the first time Deerpark CBS has experienced what he calls “paranormal activity.” He said that there was one occasion when a staff member spent the night to keep an eye on some exotic birds there for a show.

“That person left the school in the middle of the night — they refused to stay any longer as they said that they heard ‘the last call’ being played on a trumpet,” Wolfe said. “Of course this could have just been the wind.”

But previously, one student heard crying coming from the bathroom, yet no one was there. Other witnesses claim to see lights in the school go on and off during the night. And some staff members claim that the hallway captured in the video had been extra cold in the days prior to the ghost sighting.

So next time you’re complaining about taking a test, remind yourself that at least you’re not being haunted — unless you’re a student at Deerpark CBS.
