Psychological horror is a subgenre of horror that focuses on the mental and emotional states of characters rather than relying on physical threats or gore. It often explores themes of fear, paranoia, and the fragility of the human mind, creating a sense of dread through atmosphere and character development. This type of horror can leave a lasting impact by making audiences question reality and their own perceptions. In psychological horror, the tension often arises from the characters' internal struggles, such as anxiety, depression, or trauma. Works in this genre, like Shining by Stephen King or Black Swan, emphasize the psychological breakdown of individuals, leading to unsettling and often ambiguous conclusions. The horror stems from the characters' minds, making it deeply personal and relatable.
