The eerie video has already received more than 2,000 upvotes since being shared to Reddit two days ago.
It shows a white door closing shut with no one either side moving it.
While such instances can often be attributed to wind, what happens right at the end is truly creepy.
Just before the door slams shut, it stops as if being moved by an unknown force.
It then shuts sparking terror from all those watching. One woman can be seen shrieking in terror.
A dog sitting on the cameraperson’s lap also looks absolutely petrified, turning to its owner as if to ask: “What is going on?”
The clip posted by Redditor u/123darla was accompanied with the strapline: “That jaunt hesitated to close.”
Viewers were seriously creeped out, with many believing the sight was proof that “ghosts” exist.
“I don’t know about you, but I would be out the window if that happened to me,” one user wrote.
“The weird part of the video to me is the hesitation of the door before it closes.”
Another added: “The dog man. That dog was totally like… ‘dude… WTF’.”
One suggested it couldn’t have been faked because “the reaction was real enough”.
“I’m convinced it was at least not faked,” they said. “Could still be a pressure change in the house but that was a real reaction.”
The uploader also waded in to admit he would understand if people were sceptical but said it was not faked.
“If these weren’t my cousins who I know very well then I would be sceptical of this video too,” he said.
“I can see a possible explanation of it being the wind or a bad door or whatever, but I 100% believe that my cousins did not fake this.”
He also responded to people asking why it was being filmed in the first place by claiming the door “had been closing by itself” for a few days.
But one sceptic still wasn’t sure, adding: “Unless they didn’t have a single window open in this house, this has nothing to do with a ghost.”
