subconsciousness sub·con·scious·ness (sŭb-kŏn'shəs-nĭs)
The state in which mental processes take place without the conscious perception of the individual.
subconscious sub·con·scious (sŭb-kŏn'shəs)
Not wholly conscious; partially or imperfectly conscious. n.
The part of the mind below the level of conscious perception.
The part of the psyche just below consciousness and capable of bursting into consciousness. For example, a repressed sexual desire is part of our subconsciousness, although we may at some time become conscious of it.
Note: The subconscious is not the same as the unconscious. Blinking, for example, is usually unconscious and occasionally conscious, but never subconscious.
