The Uncanny by Sigmund Freud
It is not the experience itself that supplies the memory image. . . . The result . . . is that, instead of the memory image that was justified by the original experience, we are presented with another, which is to some extent associatively displaced from it. Since it was the significant components of the impression that made it objectionable, these must be absent from the memory that replaces it, and so it may well seem banal. We find it unintelligible because we would like to see the reason for its retention in its intrinsic content, when in fact it resides in the relation between this content and another, which has been suppressed. Echoing a popular phrase, one might say that, if a certain childhood experience asserts itself in the memory, this is not because it is golden, but because if has lain beside gold.
