Complex is defined as a group of associated feelings, thoughts, and memories that have intense emotional content. Complexes may have elements from a personal and collective unconscious.
To Carl Jung, Complex is a core or pattern of emotions, memories, perceptions, and wishes in the personal unconscious organized around a common theme, such as power or status. To Murray, it is a normal pattern of childhood development that influences the adult personality; childhood developmental stages include the claustral, oral, anal, urethral, and genital complexes.
