starting point for the present, and ask ourselves: If only a few of the elements of the dream thoughts get into the dream content, what conditions determine their choice?
In order to gain enlightenment on this subject let us turn our attention to those elements of the dream content which must have fulfilled the conditions we are seeking. A dream to the formation of which an especially strong condensation has contributed will be the most suitable material for this investigation. I select the dream, cited on page 142, of the botanical monograph.
Dream content: I have written a monograph upon a (obscure) certain plant. The book lies before me, I am just turning over a folded coloured plate. A dried specimen of the plant is bound with every copy as though from a herbarium.
The most prominent element of this dream is the botanical monograph. This comes from the impressions received on the day of the dream; I had actually seen a monograph on the genus "cyclamen" in the show-window of a book-store. The mention of this genus is lacking in the dream content, in which only the monograph and its relation to botany have remained. The "botanical monograph" immediately shows its relation to the work on cocaine which I had once written; thought connections proceed from cocaine on the one hand to a "Festschrift," and on the other to my friend, the eye specialist, Dr. Koenigstein, who has had a share in the utilisation of cocaine. Moreover, with the person of this Dr. Koenigstein is connected the recollection of the interrupted conversation which I had had with him on the previous evening and of the manifold thoughts about remuneration for medical services among colleagues. This conversation, then, is properly the actual stimulus of the dream; the monograph about cyclamen is likewise an actuality but of an indifferent nature; as I soon see, the "botanical monograph" of the dream turns out to be a common mean between the two experiences of the day, and to have been taken over unchanged from an indifferent impression and bound up with the psychologically significant experience by means of the most abundant associations.
Not only the combined idea, "botanical monograph," however, but also each of the separate elements, "botanical"
