whom my wife so fears. In the dream, I very freely and fully followed this desire. This far I can go in the analysis and feel sure of my ground. It will be noticed that I have not resorted to symbolism, and have made very little technical use even of the Freudian mechanisms. I could very easily plunge into symbolism and more elaborate analysis, but should I do so I fear I would be in the same condition as a bright young scholar who made an elaborate study of Freudian theories. He expressed himself by saying that it was a "chaotic inferno." This analysis will seem very unfinished to many of the well-trained readers of the JOURNAL, and so, in a way, it does to me, but it may be interesting as the work of a layman rather than a trained physician. I have not used the word "sexual" in this paper, but the reader can judge for himself if the impulses would come under this heading, either in the more narrow use of the term or in the broader meaning which Freud has given it. For myself, I see no possible objection in employing the word "sexual" in this connection. The uncertain parts of the dream are as interesting in a way as the others. Why did I not know with whom I was riding, and why were the persons with whom I talked more certain in their identity? Here, of course, is the place where it would be easy to find a repression if such existed and--I believe--if it did not exist. Whether there is such a repression there or not I do not know, but I see no necessity for considering that there is one there just because there is a dim place in the dream. In the study which I made of dreams a year or so ago, I became convinced that there is a principle of dream-making which has not been noticed. I will throw out a suggestion here in the hope that some one will study it further, but will give no elaborate discussion in this paper. Briefly, it is that only those things appear in a dream which are necessary to express the meaning of the dream. A few illustrations may make this clear. Every one has noticed the rarity with which colors and sunshine appear in dreams; I have found, however, that colors and sunshine always appear if there is any necessity for their doing so. Some one dreams of a melon and looks to see if it is ripe; he sees the red color; he dreams of a stream which he thinks is a sewer and smells it to see if it gives off an odor and finds that it does; he dreams of pulling his fishing line to see if there is a fish on it and senses the pull of the fish; I have examples in abundance which go to indicate that taste, smell, tactual, kinaesthetic, color sensation or any other kind will appear in a dream when they are called for to complete the meaning of the dream, but they are not common because they are very rarely needed. Even in waking life we rarely think in these terms. If this little principle prove true, it would be easy to understand why certain parts of a dream are dim without going to the doubtful process of positing a repression.
