The Interpretation of Dreams by Sigmund Freud Chapter 2 Page 12

Thus, for instance, a woman dreamt of herself carrying a tall flower-stalk, as in the picture of the Annunciation (Chastity-Mary is her own name), but the stalk was bedecked with thick white blossoms resembling camellias (contrast with chastity: La dame aux Camelias).

A great deal of what we have called “dream condensation” can be thus formulated. Each one of the elements of the dream content is overdetermined by the matter of the dream thoughts; it is not derived from one element of these thoughts, but from a whole series. These are not necessarily interconnected in any way, but may belong to the most diverse spheres of thought. The dream element truly represents all this disparate matter in the dream content. Analysis, moreover, discloses another side of the relationship between dream content and dream thoughts.
