Many brainteasers and optical illusions are making the rounds online.

Earlier this week, an optical illusion with a "secret" message hidden inside a square made up entirely of dots freaked out the internet because it "disappears" once you see it.

The optical illusion was posted on TikTok by user @HecticNick, who challenged people to identify what the hidden message says.

The image showed hundreds of black dots, varying in size, on a white background.

For those who couldn't crack it, the message inside the optical illusion says: "The more you look, the less you see."

The image shows a bubblegum pink square with a darker pink circle inside, that was captioned: "Can YOU See The Hidden Image?! Let me know."

Some claimed to see a number of objects: a bed, a smile and even a boat.

But the majority who reported seeing an image in the circle said they could make out the shape of a bottle.
