Many of the most effective horror films involve blurring the lines between waking life and a nightmare. When women in horror are emotionally and psychologically manipulated – whether by other people or more malicious supernatural forces – viewers are pulled into their inner worlds, often left with a chilling unease and the question of where reality ends and the horror begins.

Whether it's the havoc wreaked on the human body during pregnancy, emotional turmoil producing tiny murderous humans or simply a body turning on its owner, body horror films tend to be shocking. But while they're full of grotesque imagery, they're also full of thoughtful premises and commentary, especially when it comes to women, trauma, and power.
