Freud’s three levels of consciousness are conscious, preconscious, and unconscious. In Freud’s model of the mind, the conscious mind is formed by thoughts and feelings that a person is actively aware of and can reason. The preconscious mind is made up of all available memory that has not been accessed by the conscious mind.
The unconscious mind consists of reprised instincts, feelings and urges that are negative and shameful. Freud theorized that the preconscious and unconscious exert a powerful influence over the conscious mind without a person's awareness. Freud’s psychoanalytic theory teaches that the unconscious mind can change through the use of psychoanalysis.
