The Wikipedia describes a shadow being as an alleged paranormal entity while paranormal researcher, Heidi Hollis, has expressed the belief that shadow people are malevolent supernatural entities and described them as dark silhouettes with human shapes and profiles that flicker in and out of peripheral vision. Some people reported the figures attempting to jump on their chest and choke them.
The following is a true account. "Only recently I was told of a group of friends driving to a night out at Walsall in the UK, somewhere on their journey they saw crouched by a tree a large figure covered in spots, they estimated it would be quiet tall if it stood up, they did not stick around to get a better description; they were very un-nerved by their encounter and sped off into the night.
I have never forgotten a story a close friend of ours told us. Some years back before she was married she and her sister had gone to their local Pub, just a short walk away from where they lived with their parents. It was the journey home where things took a strange turn. They had to walk by a long wall which flanked the pavement, at some point on this walk our friend looked behind her, and what she saw caused her to freeze with fright. From atop of the wall not too far away a totally black figure dropped to the ground in a crouching position with its fingers splayed claw like, she saw no facial features as the figure was a complete silhouette. She turned to her sister and said ‘Do not look just run’, and they did; all the way home."
Heidi Hollis believes that shadow beings can be repelled by using "the name of Jesus".
