In 2010, the apparitions were described as one of the most regularly reported paranormal phenomena in the United States. This is attributed to occasional reports on the Coast to Coast AM show, where paranormal researcher Heidi Hollis has been interviewed several times on the subject of shadow people. Hollis believes that shadow people have always existed, that they feed upon emotions of fear, and that they can be repelled by thinking positively.Others believe that shadow people may be the extra-dimensional inhabitants of another universe.
The stories of shadow people have been compared to those of the Raven Mocker, a witch from Cherokee Indian mythology who sometimes appears as a shadowy phantom, and the Islamic Jinn.
Several scientific principles can be used to explain reports of apparitional experiences such as shadow people. These include optical illusions or hallucinations brought on by physiological or psychological circumstances, drug use or side effects of medication, and the interaction of external agents on the human body. Another reason that could be behind the illusion is sleep deprivation, which may lead to hallucinations.
The most believed theory is that Shadow People are spirits with dense energy, like orbs and vortexes. Some photos show that orbs and vortexes do occasionally cast shadows. All though we can’t see orbs or vortexes with our naked eye, it’s believed we can sometimes see the shadows they cast. essentially, this theory explains that the Shadow People we actually see represents the energy of the spirit that we can’t see with our naked eyes.
Another theory is that we’re getting a glimpse into another dimension. Perhaps that dimension or realm blends in with ours a bit and what we’re seeing is the shadow of someone from the other dimension. If that’s the case, then can that person see us? Do we appear like a shadow to them? Many paranormal investigators are intrigued by this theory. Unfortunately though, there’s really no way to prove it.
When it comes to Shadow People, all we can do is theorize and speculate. Perhaps all explanations are equally valid. Maybe Shadow People don’t have just one origin. While they mostly appear to be “human” outlines, there are still some that are witnessed in different sizes and shapes. Unfortunately, they go away as quickly as they appear, so nobody ever really gets a good look at them. They are strange though. One good thing that can be said about Shadow People is that, for the most part, witnesses don’t report any feelings of negativity coming from them. Shadow People leave witnesses feeling strange, and maybe a bit uneasy, but hardly ever frightened
