A creepy humanoid ice figure
You’d be surprised at the number of natural phenomena we can find menacing. It turns out that we perceive any figure that looks eerie as a threat. That triggers a fear response in our brains, inducing us to run away from the danger. Even something as simple as an ice figure can scare us.
The humanoid figure in the picture is nothing more than frozen water. We don’t know how it acquired that particular shape, but there’s no doubt it’s made of ice. However, we associate the natural phenomenon with a spirit or a demon and immediately feel a pit growing in our stomachs.
