In other cases, a witness may just be interpreting a regular shadow as something paranormal, simply because their environment has them a little spooked. Oftentimes, people report seeing a shadowy figure out of the corner of their eye. In these instances, their eye may be catching something not quite clear and their brain fills in the gap by showing something that may be more recognizable, such as the shape of a human figure. Others may simply be hallucinating as a result of some underlying condition.
But these scientific explanations don’t explain any of the images of shadow people that investigators claimed to have caught on camera. Having looked at some of these images, it’s pretty clear that in many cases there could be other explanations for the dark mass appearing in the image. But in a few cases, it can be hard to argue that what we’re seeing could indeed be something we can’t explain.
As to exactly what shadow people are or if they even exist, we’ll probably never know for sure.
