Shadow people are said to usually appear in a person's peripheral vision, darting away upon being seen; however, there are rare circumstances when people have come face to face with the shadow people. They are also known as shadow men and shadow folk.
“ Shadow People: Who are they? Shadow people (also known as Shadow men, Shadow folk or Shadow beings) are said to be shadow-like creatures of supernatural origin which appear as dark forms in the peripheries of people’s vision and disintegrate, or move between walls, when noticed. Reports of shadow people are similar to ghost sightings, but differ in that shadow people are not reported as having human features, wearing modern/period clothing, or attempting to communicate.
