Here the matter rests. We need not give up the results of our work of dream-interpretation, even though we cannot fail to find them strange. Perhaps later we shall be able to come nearer to understanding them by another path. For the present let us hold fast to this: dream-distortion is due to the censorship exercised, by certain recognized tendencies of the ego, over desires of an offensive character which stir in us at night during sleep. Obviously, when we ask ourselves why it is just at night that they appear and what is the origin of these reprehensible wishes, we find that there is still much to investigate and many questions to answer. It would, however, be wrong if we neglected to give due prominence at this point to another result of these investigations. The dream-wishes which would disturb our sleep are unknown to us; we first learn about them by dream-interpretation; they are therefore to be designated “unconscious at the moment” in the sense in which we have used the term. But we must recognize that they are also more than unconscious at the moment; for the dreamer denies them, as we have so frequently found, even after he has learnt of them through the interpretation of his dream. Here we have a repetition of the case which we first met with when interpreting the slip of the tongue “hiccough,” where the after-dinner speaker indignantly assured us that neither then nor at any time had he been conscious of any feeling of disrespect towards his chief. We ventured even then to doubt the value of this assertion and assumed instead that the speaker was permanently ignorant of the existence of this feeling within him. We meet with the same situation every time we interpret a dream in which there is a high degree of distortion, and this lends an added significance to our conception. We are now prepared to assume that there are processes and tendencies in mental life, of which we know nothing; have known nothing; have, for a very long time, perhaps even never, known anything about at all. This gives the term _unconscious_ a fresh meaning for us: the qualification “at the moment” or “temporary” is seen to be no essential attribute, the term may also mean _permanently unconscious_, not merely “latent at the moment.” You see that later on we shall have to discuss this point further.
