[Footnote 81: Thus far this explanation of _Déjà vu_ has been appreciated by only one observer. Dr. Ferenczi, to whom the third edition of this book is indebted for so many contributions, writes to me concerning this: “I have been convinced, through myself as well as others, that the inexplicable feeling of familiarity can be referred to unconscious fantasies of which we are unconsciously reminded in an actual situation. With one of my patients the process was apparently different, but in reality it was quite analogous. This feeling returned to him very often, but showed itself regularly as originating in a forgotten (repressed) portion of a dream of the preceding night. Thus it appears that the _Déjà vu_ can originate not only from day dreams but also from night dreams.”] [Footnote 82: I can perhaps give the following outline concerning the mechanism of actual forgetting. The memory material succumbs in general to two influences, condensation and disfigurement. Disfigurement is the work of the tendencies dominating the psychic life, and directs itself above all against the affective remnants of memory traces which maintain a more resistive attitude towards condensation. The traces which have grown indifferent merge into a process of condensation without opposition; in addition it may be observed that tendencies of disfigurement also feed on the indifferent material, because they have not been gratified where they wished to manifest themselves. As these processes of condensation and disfigurement continue for long periods during which all fresh experiences act upon the transformation of the memory content, it is our belief that it is time that makes memory uncertain and indistinct. It is quite probable that in forgetting there can really be no question of a direct function of time. From the repressed memory traces it can be verified that they suffer no changes even in the longest periods. The unconscious, at all events, knows no time limit. The most important as well as the most peculiar character of psychic fixation consists in the fact that all impressions are on the one hand retained in the same form as they were received, and also in the forms that they have assumed in their further development. This state of affairs cannot be elucidated by any comparison from any other sphere. By virtue of this theory every former state of the memory content may thus be restored, even though all original relations have long been replaced by newer ones.] [Footnote 83: Cf. here _The Interpretation of Dreams_, p. 483.
