Solution:According to the psychoanalytical theory, famously developed by Sigmund Freud, the human mind operates at three levels: the conscious, the preconscious, and the unconscious levels. The conscious level includes thoughts and perceptions that are currently in our awareness.
The preconscious level contains memories and thoughts that are not currently in consciousness but can be brought into consciousness. Lastly, the unconscious level houses a vast reservoir of feelings, thoughts, urges, and memories that are outside of our conscious awareness.
These are often unpleasant or unacceptable sexual desires, violent motives, irrational wishes, shameful experiences, and fears.
