In the ancient days, magic practitioners or any occult studies would come in contact with these beings. The funny thing is that these beings were written about ages ago and there's an increase of people reporting them. As far as I see it the shadow people are entities known as fliers or archons. Some believe these beings are within our own mind, which I believe too in having 2 minds. I've caught a few in the corner of my eyes. And it exactly the way of how some people explained it. Fleeting shadows. Beings feeding off our emotional energies which come from astral realms. Anyone have experience with shadow beings?
