Do you believe in ghosts? If not, this video may change your mind.

CCTV footage from Deerpark school in Cork, Ireland shows something unusual happened around 3 a.m. on October 1.

Some are suggesting that paranormal activity is responsible for doors opening and slamming, lockers being flung open and a sign being knocked over. Naturally, some critics are suggesting this is an obvious prank, but the school's principal, Aaron Wolfe, says otherwise.

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.

Principal Wolfe also said a staff member spent the night at the school to tend to some exotic birds on one occasion and left school in the middle of the night after hearing music played on a trumpet.

Lights have also been known to flicker on and off in the night and students have reported hearing the sound of crying in the bathroom but found no one inside. Staff members have even said it felt colder in the school after paranormal activity was reported.

Do you think something eerie is happening in the school, or is it just a prank?
