It could just be a trick of the light. But the terrifying face in this picture could be something more sinister.
At first glance, there is nothing untoward and the image has divided the internet between the people who can see it, and those who cannot.
Once it is pointed out, however, it is difficult to take your eyes away from the face that suddenly becomes clear.
The origins of the picture are unclear, but it's possible that it was actually created by someone hiding behind the cushion while being photographed.
Or it could be something that somebody has been created using Photoshop.
However it was made, it is hard to look away or get the image out of your head.
