Shadow Person
Manifesting as shapeless, dark masses with no human features, mostly seen in the peripheral vision, shadow people move between walls, just generally causing a feeling of dread.
Spectre
A spectre, often referred to as a ghost, typically manifests as a human being, sometimes almost transparent in nature. However, a spectre isn't real and usually terrifies the person who sees it. Spectres, like most hauntings, typically appear at night.
Demon
Demons are fallen angels that never had a mortal human form and instead are pure energy entities. They can manifest as angels, hideous creatures, or just a black mist. Either way, their main purpose is to cause chaos and havoc upon mankind. Demons are deceivers, and they manipulate people to do things they'd never dream of.
Poltergeist
Poltergeists channel the energy from others and turn it into physical manifestations, including tapping sounds, the movement of objects, lights flickering off and on, cupboards opening and closing, and more.
