At first glance, this family photo looks completely innocent. It’s just a mother and father with their four children proudly posing for a picture.

But social media users quickly noticed something hidden in the image, and it’s not what you’d expect.

As you can imagine, the post has quickly gone viral, as people try to work out what’s wrong with it. And when you actually find it, it’s pretty scary.

There’s a person hiding in the sofa. If you look closely, you’ll see an eye staring out from beneath the cushions.

Have you found it yet? Just under the mother’s leg is the image of another man’s face. And what’s worse is the family appears to be completely unaware of his presence.

A bit sinister for a family photo, don’t you think?

It’s not the first time an image has gone viral for the wrong reasons. Recently, Twitter freaked out after a photo appeared to show a face on the back of a woman’s head.

“What kind of devilish, demonic thing is going on here?” one social media user asked. “I’m scared but laughing,” said another.
