A TIKTOKER has revealed a trippy optical illusion that changes the way you see things within seconds.
The video by Michael Khieu has already been liked well over 20,000 times.
It’s very simple – just focus on a red dot in the middle of the screen.
You’ll need to stare at it for 15 seconds without blinking.
All the while, black and white lines will wobble in the background.
Once the 15 seconds are up, look around the room and you’ll notice something quite strange.
“Do not blink!” the TikToker says.
“Stare at the centre and try not to look away.”
If it’s worked, everything you’ll see will become a bit wavy.
But it only lasts temporarily.

“I see the wave effect,” one user said.
“My walls are stretching,” another commented.
A third added: “Everything was expanding.”
However, not everyone could get the trick to work, so you might have to try again and focus a bit harder on the dot.
