The Interpretation of Dreams
1899 written work by Sigmund Freud

The Interpretation of Dreams (German: Die Traumdeutung) is an 1899 book by Sigmund Freud, the founder of psychoanalysis, in which the author introduces his theory of the unconscious with respect to dream interpretation, and discusses what would later become the theory of the Oedipus complex. Freud revised the book at least eight times and, in the third edition, added an extensive section which treated dream symbolism very literally, following the influence of Wilhelm Stekel. Freud said of this work, "Insight such as this falls to one's lot but once in a lifetime."
Dated 1900, the book was first published in an edition of 600 copies, which did not sell out for eight years. The Interpretation of Dreams later gained in popularity, and seven more editions were published in Freud's lifetime.
Because of the book's length and complexity, Freud also wrote an abridged version called On Dreams. The original text is widely regarded as one of Freud's most significant works.
Background
Freud spent the summer of 1895 at Schloss Bellevue near Grinzing in Austria, where he began the inception of The Interpretation of Dreams. In a 1900 letter to Wilhelm Fliess, he wrote in commemoration of the place:
Do you suppose that some day a marble tablet will be placed on the house, inscribed with these words: 'In this house on 24 July 1895, the secret of dreams was revealed to Dr. Sigm. Freud'?

Why this record matters
The phrase “1899 written work by Sigmund Freud” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 25, 2026. The linked authority identifier is Q726382. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1899, 1900 and 1895.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
