Viewers were spooked after a creepy voice interrupted a broadcast of Queen Elizabeth's funeral.
UK broadcaster ITV was bringing viewers live footage of the Queen's hearse on its way to West London when a ghostly unidentified female voice interrupted.
"The death is irreversible… The fact that she's trapped," the voice whispered in an unverified clip of ITV's coverage.
The male commentator paused and then continued to narrate the journey, not acknowledging what had just occurred.
Theories erupted on social media from another crew member whispering during the feed, a banshee or even the late Princess Diana's ghost being behind the mysterious voice.
Whatever it was, it sure has people creeped out.
"What was that?!" One person tweeted.
"That is terrifying," another person commented.
"This gave me the heebies this morning," a third said.
Unscripted moments during the Queen's funeral have been making global waves.
An spider crashing the funeral and Australian presenters mistaking UK Prime Minister Liz Truss for a "minor royal" got people on social media talking.
It is estimated that billions of people worldwide tuned in to at least some of the Queen's funeral as the nation said their final farewells to Her Majesty on Monday.
