content according to an established key; I am much more prepared to find that the same dream may cover a different meaning in the case of different persons, and in a different connection I must then resort to my own dreams, as an abundant and convenient material, furnished by a person who is about normal, and having reference to many incidents of everyday life. I shall certainly be with doubts as to the trustworthiness of these “self-analyses.” Arbitrariness is here in no way avoided. In my opinion, conditions are more likely to be favourable in self-observation than in the observation of others; in any case, it is permissible to see how much can be accomplished by means of self-analysis. I must overcome further difficulties arising from inner self. One has a readily understood aversion to exposing so many intimate things from one’s own psychic life, and one does not feel safe from the misinterpretation of strangers. But one must be able to put one’s self beyond this. “Toute psychologiste,” writes Delbœuf,[26] “est obligé de faire l’aveu même de ses faiblesses s’il croit par là jeter du jour sur quelque problème obscure.” And I may assume that in the case of the reader, the immediate interest in the indiscretions which I must commit will very soon give way to exclusive engrossment in the psychological problems which are illuminated by them. I shall, therefore, select one of my own dreams and use it to elucidate my method of interpretation. Every such dream necessitates a preliminary statement. I must now beg the reader to make my interests his own for a considerable time, and to become absorbed with me in the most trifling details of my life, for an interest in the hidden significance of dreams imperatively demands such transference.
