The paranormal and the fear of the unknown is naturally a classic topic of horror. Gathering everything from ghost to demons and even witches, it is usually the part of horror cinema that gets the scariest results. Ghost
Ghosts, specters, or spirits need no introduction since their existence in film is not new. In horror cinema, they are usually the soul of the dead which, for whatever reason (unfinished business and revenge are the most common) don't flow peacefully go to the hereafter but stay on Earth to haunt us.

This one speaks for itself. The difference with the ghost sub-genre comes from the fact that the spirits here belong to the house itself, and are not focussing someone in particular. Sometimes, like in 1408, it is the room itself that is alive.

Possession/exorcism exists as a sub-genre where a body is infiltrated by an evil spirit or a demon, that takes control over that person. The genre owes its success to The Exorcist (1973), one of the most famous horror films of all time. The sub-genre gained a renewed interest in the past ten years with the release of multiple exorcism blockbusters.

Devil & Demons
Whether it is the devil itself or its demon servants, religion has always been a major source of inspiration for horror. This sub-genre often appears as a cross-over between possession and zombie film.

Feared since the early middle-ages, witches and the science of the occult naturally appear as common horror themes. Witches are mostly considered to be women, but men can be found (Warlock (1989)). In any case, witches are cruel, merciless creatures who use their paranormal power to commit evil doings.
