Ever been to an open house viewing, where you'll casually wander through the property and weigh up whether to make an offer?
That's what these unsuspecting potential home buyers thought they were in for - but they were instead lined up to be victims of a scary prank, courtesy of Paramount Pictures.
The movie studio wanted to have some fun to promote their new film 'Paranormal Activity: Ghost Dimension', the final instalment in the successful franchise, and rigged a home to scare the people inside.
The studio created a mock open house and invited in prospective buyers. The "agent" tried to keep her cool but the folks couldn't keep theirs and some ran for the door screaming and out of the house.
If the house looked familiar, it's because it was used in the original Paranormal Activity movie.
House hunters hunted
House hunters enter the property and as they're making their way around the house some spooky, unexplained things start to happen.
The 'paranormal activity' in the house begins to freak the people out. When the mirror smashes, all of the guests scamper down the staircase and out on to the street.
Oren Peli, director of the original 'Paranormal Activity' movie, posted the video to Facebook. "Can you blame me for selling my house?" he joked.
'Paranormal Activity: The Ghost Dimension 3D' premieres October 22 - just in time for Halloween!
