Paranormal investigation films revolve around themes of horror and the supernatural, featuring ghost hunters, investigators, or victims who encounter sinister afterlife entities. These films often blend reality-show elements, using video footage to validate paranormal occurrences or clear investigators' names. The genre, popularized by films like *The Blair Witch Project* (1999), pioneers the found-footage style, immersing audiences in a fictional investigative process akin to reality TV. Marketing strategies for films like *Paranormal Activity* and *The Conjuring* enhance their realism, playing on cultural paranoia and blurring the lines between documentary and fiction. This genre elicits powerful responses by creating cognitive dissonance, where viewers suspend disbelief for emotional engagement.
