freud compared our mind to an iceberg: the conscious mind is the tip of the iceberg and the small amount we know about mental activity, the preconscious is just under the surface, they are things we could acknowledge if we tried or wanted to, sometimes these things come to light. Finally, the unconscious is the bottom of the iceberg and are the things we are unaware of and cannot become aware of like unacceptable sexual desires and immoral urges
