The term 'abnormal fear' can be summarized as a PHOBIA, which is an irrational and intense fear of certain objects or situations. Phobias are often caused by a traumatic event or experience, and can lead to avoidance of the feared object or situation. People with phobias may experience physical symptoms such as sweating, trembling, and difficulty breathing when exposed to the feared object or situation. Treatment for phobias typically involves cognitive-behavioral therapy, which helps individuals to identify and modify their thoughts and behaviors related to the fear.
