Who Are The Shadow People?

You're alone, engrossed in some activity until you arbitrarily turn your head. There is a dark figure standing in the shadows only yards away, watching you. You really don't notice until it moves; faster than you can turn your head. Was someone there? You dismiss this as some peculiar anomaly of your own questionable eyesight. Regardless, you can't shake the feeling someone was standing there, Lord knows how long, watching you.
For those of you who don't know, Shadow people often appear as the silhouette of a person; presumably male and generally lack any other features. However, there have been recent reports of shadowy figures wearing hoods, fedoras and overcoats. Some even claim to have witnessed dark red eyes. And everyone seems to agree, they are wicked, evil and malicious.
However, because there are so many different types of contradicting sightings, the common assumption among non-believers is they're imaginary. Science has even come up with a number of possibilities that explain away this phenomenon. Not accounting for the possibility, under certain conditions the Shadow people can be seen.
Currently, millions of people are stuck in limbo with unanswered questions. But what if I were to tell you, many of the Shadow people have always wanted to provide answers! They speak without speaking; they need special people to hear them. Am I such a person? All I can do is share more than 25-years of personal experiences, interactions, gained knowledge and journeys with the Shadow people; then let you decide.
