This document discusses the typical conventions of several horror subgenres, including supernatural, gothic, possession, and slasher films. For supernatural films, it notes that they are often set in isolated homes of the main characters where a supernatural presence is unwelcome. Gothic films commonly use gloomy settings like castles and churches with secret areas. Possession films typically have isolated locations like abandoned buildings with a hidden dark history. Slasher films feature quiet suburban towns as settings and involve an unknown killer in a mask who uses weapons to kill victims after disabling their means of escape. The document provides examples from films to illustrate these conventions.
