The human eye can be tricked pretty easily. Photographer Anelia Loubser made use of this simple fact and created her Alienation series where she photographs human faces upside down and extremely closeup to create creepy optical illusions.
After scrolling through all of these photos, you might not be able to see normal human faces anymore, instead you will ask yourself if it’s not actually an alien that is staring right at you.
