Freud provides a theoretical framework for understanding the unconscious mind, which includes concepts such as the id, ego, and superego. The id is the primitive, irrational part of the mind that is driven by impulsive desires. The ego is the part of the mind that mediates between the id and the outside world, serving as a realistic and practical component. The superego represents the ethical standards and ideals that are internalised from society, and it serves as a moral guide for the ego. These concepts provide a foundation for understanding the dynamics of the unconscious mind, and the role it plays in shaping our dreams.
