The answer is B: Shadow.
Explanation for each option:
A) Self: In Jungian psychology, the Self represents the unification of the conscious and unconscious parts of the psyche. It is the central archetype that signifies the whole of the psyche, integrating all aspects of an individual's personality. It is not typically associated with dark or wild figures like dragons or demons.
B) Shadow: The Shadow archetype in Jungian psychology embodies the darker, unconscious aspects of the personality. It includes repressed weaknesses, desires, and instincts. The Shadow often appears in dreams as dark, wild, or threatening figures, such as dragons or demons, symbolizing the parts of ourselves that we do not wish to acknowledge.
C) Anima: The Anima is the feminine aspect of a man's unconscious mind, while the Animus is the masculine aspect of a woman's unconscious mind. These archetypes are more about gender and relational dynamics rather than dark or wild figures.
D) Persona: The Persona is the social mask or role that an individual presents to the outside world. It is the part of the personality that is shown to others, often to conform to societal expectations. It is not associated with dark or wild figures in dreams.
Therefore, the Shadow is the correct answer as it represents the darker, instinctual side of the psyche that can manifest in dreams as threatening or wild figures.
