8. You will remember that we once hoped to gain access to the understanding of the dream problem by the fact that certain very transparent phantasy formations are called _day dreams_. Now these day dreams are actual wish fulfillments, fulfillments of ambitious or erotic wishes with which we are familiar; but they are conscious, and though vividly imagined, they are never hallucinatory experiences. In this instance, therefore, the less firmly established of the two main characteristics of the dream holds, while the other proves itself entirely dependent upon the condition of sleep and impossible to the waking state. In colloquial usage, therefore, there is a presentment of the fact that the fulfillment of a wish is a main characteristic of the dream. Furthermore, if the experience in the dream is a transformed representation only made possible by the condition of sleep--in other words, a sort of nocturnal day dream--then we can readily understand that the occurrence of phantasy formations can release the nocturnal stimulus and bring satisfaction. For day dreaming is an activity closely bound up in gratification and is, indeed, pursued only for this reason. Not only this but other colloquial usages also express the same feeling. Well-known proverbs say, "The pig dreams of acorns, the goose of maize," or ask, "Of what does the hen dream? Of millet." So the proverb descends even lower than we do, from the child to the animal, and maintains that the content of a dream is the satisfaction of a need. Many turns of speech seem to point to the same thing--"dreamlike beauty," "I should never have dreamed of that," "in my wildest dreams I hadn't imagined that." This is open partisanship on the part of colloquial usage. For there are also dreams of fear and dreams of embarrassing or indifferent content, but they have not been drawn into common usage. It is true that common usage recognizes "bad" dreams, but still the dream plainly connotates to it only the beautiful wish fulfillment. There is indeed no proverb that tells us that the pig or the goose dreams of being slaughtered. Of course it is unbelievable that the wish-fulfillment characteristic has not been noted by writers on the dream. Indeed, this was very often the case, but none of them thought of acknowledging this characteristic as universal and of making it the basis of an explanation of the dream. We can easily imagine what may have deterred them and shall discuss it subsequently.
