Ghost of a Roman Captured on Camera: Paranormal Sightings

This isn’t your average haunting. Inside this home, something dark has taken hold — and it’s not hiding anymore. Disembodied voices echo from empty rooms. Objects move with no explanation. A ball literally manifests out of thin air. Faucets turn on by themselves. And if you look closely… you’ll see its shadow reflected in the fridge. This is true poltergeist activity — and I believe it’s demonic. Watch closely… and don’t watch alone. #paranormal #demon #poltergeist #haunted #scary
