There are four people in this optical illusion and it’s creeping everyone out

The internet does love a good optical illusion.

A photo has gone viral on social media because people cannot see the fourth person in the picture.

The debate started when @JenMsft tweeted the image of four bottles being clinked on what looks to be a group hike.

But only three arms are immediately visible.

She commented: “My brain refuses to believe there are 4 people in this photo.”

For those struggling to see them all, the “missing” fourth arm appears to be camouflaged as the bottle holder’s jacket matches the rocky path the group are standing on.

User @JenMsft said the photo was first shared in a Reddit thread on confusing perspectives.

People have previously looked into other optical illusions such as a hand swap trick, disappearing patterns and classic dual perception images.

Social media users reacted to the latest confusing picture to go viral.

Someone handily zoomed-in on the photo to highlight the illusion.

Others shared their favourite optical illusions.
