The bizarre video shows the mannequin sitting on a seat and looking out a shop window.
It is facing away from the person filming but then something truly bizarre happens.
With no one visibly around it, the inanimate object appears to turn towards the camera.
The footage was originally posted by YouTube channel Obscura in April, but has been picked up by popular channel Disclose Screen this week.
“Was that a trick of the camera?” he asked.
“I’ve looked at this pretty hard and there are no obvious signs of manipulation.
“Does this mannequin have robotic parts?”
Viewers were quick to voice their thoughts, with one writing: “Man that was creepy to watch.”
Another commented: “The mannequin clip looks creepy but I’m pretty sure It’s just a raindrop on the car window.”
And a third was also sceptical, adding: “The mannequin is a person in one of those elastic suits that cover the body.
“It’s a total setup.”
It is not the only spooky footage to have emerged in recent weeks.
Some claimed a mysterious happening at a workshop that was caught on CCTV this week was proof ghosts are real.
