"The dream censorship functions to preserve sleep by controlling the expression of unconscious wishes, and reventing the generation of unpleasant affect. The inhibition of affect...must be considered as the second consequence of the censorship of dreams, just as dream-distortion is its first consequence It should be noted that while it is the censorship that necessitates dream distortion, the censorship itself does not actually carry out the distortion, This is done by the dream-work. The work of the censorship is merely to prevent unconscious wishes from entering the preconscious, or from linking up with preconscious wishes. Only if the unconscious wishes can be sufficiently disguised by the dream-work will the censorship permit the compromise formation to be experienced as part of the dream."
