A word of warning, don’t look at this optical illusion after dark.
Internet users have been reporting seeing freaky faces when they look at one of the latest optical illusions to captivate people.
The video simply asks people to say how many faces they see, but people have been reporting seeing some scary effects, as well as disputing how many faces they can actually see.
So, if you dare, take a look at the video below and tell us how many faces you see.
This is everything you need to know about an optical illusion from Tik Tok.
What does the video show?
The video shows several faces, some on the left and some on the right, with a cross symbol in the middle of the two.
Nick advised viewers to “focus your eyes in the middle of these two pictures”.
The cross symbol marks the spot where viewers should focus.
On each side of the focal point viewers then see rapidly-shifting videos of faces.
The faces on the left and right sides weren’t identical, but on a passing glance they look very similar.
Nick advised: "Your mind is going to try to combine them together.
"While you’re looking in the middle, the pictures on the sides are going to look really strange.”
