A couple walking their dog claims to have encountered something quite frightening when a sinister-looking creature suddenly crossed in front of them in the dark. Despite having captured the incident on camera, they are unsure of what it is.

This month, Hannah Rowett and Dave Rowett were wandering through Clumber Park in Nottinghamshire, England with their dogs when they almost ran into the mysterious thing. You can watch it materialize seemingly out of nowhere, cross their path, and then vanish.

People are split on whether or not the eerie clip is real or just a well-edited video after the pair shared it on Facebook, where it has gained significant attention.

Even though Dave regarded to himself as a skeptic of ghosts, he claims that this experience converted him.

For your information, Clumber Park is said to be haunted by a ghost known as “Grey Lady” who manifests as a woman in a long cloak who is frequently characterized as a demon and crawls on her long limbs. This description fits the hunched-over object shown in the video rather well.
