Dream Censor

The Censor and the Disguising of Dreams

In The Interpretation of Dreams (1900), Freud used the word censorship to explain why a dream does not show an unconscious wish as it is. The censorship sits as a checkpoint between the unconscious and the preconscious, and it does not let a morally or socially unacceptable wish through in its own shape. The energy of a wish cannot be held back completely, however, so the censorship compromises and admits images that have changed their appearance. The dream censor, then, is drawn not as a wall that blocks the wish but as a gatekeeper who rebuilds it into something unrecognizable and lets it pass. Once the later structural model (ego, superego, id) was in place, the work of this checkpoint came to be discussed on the side of the superego and the resistances of the ego.

How the Disguise Gets Made (Condensation, Displacement, Symbolization)

Freud called the operations that rework latent content into manifest content under the pressure of censorship the dream work (Traumarbeit). Condensation bundles several thoughts into a single image, which shows up as one figure in a dream carrying the features of several people at once. Displacement moves the emotional weight off the real subject and onto something trivial, shifting where the dream appears to be pointing. Symbolization swaps an abstract wish for the shape of a concrete object. Because these overlap, the manifest content ends up far from the latent content, and the original meaning is hidden even from the dreamer. The count varies by source, and some treatments fold in the secondary revision described below. Rather than memorizing how many devices there are, it helps more to notice that all of them push in one direction: changing the appearance without diluting the meaning.

Secondary Revision and Anxious Dreams

Freud also said that the strength of the censorship is not constant. Inside that framework, anxious dreams and nightmares are explained as a state in which something held down has slipped past the disguise and reached consciousness, a failure of the censorship.

The other item worth naming is secondary revision. It refers to the work by which scattered images are tidied up until the dream holds together as a story. The tendency to smooth out the plot while telling a dream to someone can be seen as its continuation. That is why a dream record keeps more clues if you leave it as the fragments you had on waking rather than turning it into a coherent summary.

What Use the Idea of Censorship Still Has

The censoring apparatus itself has not been supported by dream research from the later twentieth century onward. Brain imaging has shown activity in the dorsolateral prefrontal cortex dropping during REM sleep, and the leading position became that the strangeness of dreams can be explained without invoking an agent who censors, as reduced activity in the regions that handle judgment and self-criticism. What has stayed is the clinical observation that emotionally heavy matters appear in dreams swapped for something else, and it is reread within the framework in which sleep takes part in processing emotion (the emotion regulation hypothesis).

Brought back to the practice of dream reading, the use of this concept comes down to one point: what you can see is not necessarily the subject. The person or the scene in the dream is not always the person or the scene on your mind, and it can be the feeling that is hard to say out loud which has been moved onto another object. Handled carelessly, though, this way of reading turns dangerous. Any dream at all can be told that its real meaning lies elsewhere, and the interpretation stops being falsifiable. As a brake, once you have built a story about the substitution, always check it against concrete events in your waking life. If it does not mesh, you are free to drop the reading. A dream is not a diagnosis, and the metaphor of a censor cannot settle anything about your character or your health.
