Explanation:
Sigmund Freud has discovered the three distinct levels of an individual's mind including conscious, unconscious, and the subconscious in his psychoanalytic theory.
Unconscious: In psychology, the term unconscious is defined as a reservoir of thoughts, memories, urges, and feelings that are outside an individual's conscious awareness yet the person gets affected with the same. Freud argued that most of the components of an individual's unconscious mind are unpleasant like feelings of conflict, pain, and anxiety, etc.
