The fear of Halloween is called Samhainophobia. It is a specific phobia disorder, which is an intense and persistent fear of a specific situation or object that is not harmful in reality. People with Samhainophobia feel anxious when they think about or experience anything related to Halloween, including costumes, decorations, and traditions. This phobia can be triggered by past traumatic situations related to Halloween, fear of death, or exposure to scary images and movies. Symptoms of Samhainophobia include panic attacks, nausea, dizziness, and avoidance of Halloween-related activities. Exposure therapy, cognitive-behavioral therapy, and hypnotherapy are some of the treatments that can help overcome Samhainophobia.
