Is this the ghost in the mirror prank to end all ghost in the mirror pranks? (Yes, it's totally a thing!) Imagine that you're getting your hair cut, watching the stylist as they go about their business in the mirror. Then you see it: a ghostly girl in the mirror. Yeah, we would react just as these ladies in the video do. And that's not even the worst part. The girl then proceeds to walk about into the salon doing a terrifying backbend. But don't worry: It's all the name of promoting the horror flick Last Exorcism 2. While there are no real ghosts in this video, it's still pretty darn creepy!
