A plane optical illusion has left people scratching their heads as they claimed they nearly 'landed' the aircraft themselves after witnessing the mind-boggling brain teaser.
The image was shared on X, formerly known as Twitter, and depicted a passenger who people on the web compared to 'ET'.
The snap sparked a shocking debate about what was really going on in the 'creepy' illusion.
At first glance, the picture looked like a man who had turned his head completely to the side and was staring at a fellow passenger.
The mind-boggling image left people stumped as they even claimed they got 'scared' by it.
However, while the image may appear chill-inducing, it's much more innocent than it seems.
Teasers can help improve your observation skills and sharpen your mind but they take practice, so are you able to spot what is actually going on in the image?
The snap was taken by a passenger on a plane.

Were you able to figure out what was going on in the puzzling snap?
Here's a hint, look closer at what seems to be the eyeball.
Although it looks like a man with a mustache is staring at you, the person actually has a hoodie on backward over their face.
The part of his face that looks like an eyeball is a headphone.
Even though it looks like the passenger is giving you an eerie look, their face is actually turned to the side and they have headphones in their ear while the hoodie covers their face.
Optical illusions are said to help improve your concentration skills while also improving the ways your brain and eyes work together.
