Phobia, also known as phobic neurosis, is a neurosis with fear symptoms as its main clinical manifestation.
Horror objects have special environments, people or specific things, and whenever you come into contact with these horror objects, you will have intense fear and nervous inner experiences.
The patient is conscious and knows that it is unreasonable, but once encountering similar situations, he still has recurring feelings of fear, cannot control himself, and develops avoidance behavior.
