Preconscious
The preconscious level of the mind includes all those elements that are not conscious but can become conscious either quite readily or with some difficulty.
The contents of the preconscious is drawn from two sources, the first of which is conscious perception. What a person perceives is conscious for only a momentary period; it soon passes into the preconscious when the focus of attention shifts to another idea.
The other source of preconscious images is the unconscious. Freud believed that thoughts can slip past the vigilant censor and enter into the preconscious in a camouflaged form. Some of these images never become conscious since if we recognized them as derivatives of the unconscious, we would experience amplified levels of anxiety. Other images from the unconscious might gain admission to consciousness, after cleverly disguising themselves through the dream process, a slip of the tongue, or an elaborate defensive measure.
