If there's one thing we know that can divide people on the internet, it's an optical illusion.

Whether it's a dress that nobody can decide is blue and black or white and gold, or a picture of a man who appears to be wearing heels, people love to debate what a brain-teasing snap really shows.

Case in point, this week a TikTok user going by the handle @hecticnick took to social media to share a video of an optical illusion which turned out to be pretty contentious.

The video in question shows the TikToker showing an image of a mysterious gray shape, stating: "This picture is not what you think it is."

"You’re probably seeing an ocean with the beach in front of it, right? Well, in reality, what it actually is is the bottom of a car door that’s damaged with the ground underneath it."

Take a look at the original video of the image below:

As you can see for yourself by squinting closely, the picture does indeed show the bottom of a car door, and not a beach during a stormy evening.

However, even after watching the video all the way through, there were still plenty of other TikTok users who couldn't agree on what the image actually shows.

People can't agree if this optical illusion is a picture of a beach or a car
