Now, some of these stories involve actual, physical things that happened, but often eeriness is best described as a feeling. We love spooky stories in the right context, but eeriness comes from something we can’t quite place our finger on, either literally or figuratively. For example, the uncanny valley, where something appears to be mostly human but artificial enough to put us on edge.
People with a good sense of fantasy have run rampant with the idea. Why does this instinct exist, they might ask, why do we have an evolutionary fear of something that looks almost like us? A danger-sense of aliens, skinwalkers, or something else? As much as I love these concepts, the truth is probably a bit more morbid but mundane. Corpses. We fear corpses since they are likely vectors for disease and also indicate that a human died here, meaning there is something dangerous about.

Fear itself is a pretty wide spectrum. Many of the tales here zero in on the specific feeling of chills, nervousness, and goosebumps. When we call something “chilling,” it’s not a misnomer, our body does actually feel a rush of cold. This kind of “fear” mostly comes in that gray space between truly feeling in danger and the brain starting to recognize patterns of danger. A tiger in the wild, for example, is a clear and present danger. Creepiness is more a result of the brain feeling in danger without quite knowing why.

Despite popping up when perhaps we don’t want it to, this feeling has an evolutionary advantage. Our brains are relatively clever, we can recognize patterns. Even more cleverly, we can recognize patterns that we haven’t experienced. True crime enthusiasts, for example, can be well aware of certain dangers without ever being the victim of a crime themselves. The advantage of this is that our brain will tell us we might be in danger before we consciously understand it.

That’s when the man attacked her.

On the other hand, this does mean that we also might feel in danger in situations that do not warrant it. Horror movies really do make dark rooms seem considerably more sinister than they should be. A historical recreation enthusiast is generally not something to fear, but add some fog and you have a verifiable ghost on hand. Our brains are recognizing patterns they have seen in films, which would be a useful skill if you only watched documentaries. However, it’s no surprise that the majority of media consumption is precisely fictional.

There are other evolutionary features at play as well. As sentient creatures, we recognize that there are other sentient or at least intelligent beings out there. This is sometimes called agent detection. Imagine hiking through the woods and seeing what might be the indentation of a bear’s paw print. Most humans recognize that bears can be pretty dangerous, so without even confirming it’s presence, a human will modify their behavior to protect themselves. For example, I would just go home.
