Many people find certain dolls or statues creepy, but a true irrational fear of such humanoid figures is more intense than simply feeling uneasy. Individuals with automatonophobia can have an extreme fear of wax figures, puppets, animatronics, and mannequins, and that terror can manifest with physical symptoms. Dolls are a common fear trigger, too, to the point that they've inspired their own phobia: pediophobia.
Scientists aren't exactly sure what causes fear of mannequins or dolls. Maybe it's their mimicry of life that feels a little off. Their eyes are a little too blank, their poses a little too stiff. No matter how skilled the artist who created the figure, it's always going to reside in the uncanny valley. And making humanoid forms more realistic doesn't help; features like hair and glass eyes just make mannequins even more unsettling.
If you have a mannequin phobia (or even if you don't), these creepy mannequin photos will surely horrify you.
