104 represents a wish as fulfilled. It will be our next interest to ascertain whether this is a universal characteristic of the dream, or only the accidental content of the dream ("of Irma's injection") with which we have begun our analysis, for even if we make up our minds that every dream has a meaning and psychic value, we must nevertheless allow for the possibility that this meaning is not the same in every dream. The first dream we have considered was the fulfilment of a wish; another may turn out to be a realised apprehension; a third may have a reflection as to its content; a fourth may simply reproduce a reminiscence. Are there then other wish dreams; or are there possibly nothing but wish dreams?

It is easy to show that the character of wish-fulfilment in dreams is often undisguised and recognisable, so that one may wonder why the language of dreams has not long since been understood. There is, for example, a dream which I can cause as often as I like, as it were experimentally. If in the evening I eat anchovies, olives, or other strongly salted foods, I become thirsty at night, whereupon I waken. The awakening, however, is preceded by a dream, which each time has the same content, namely, that I am drinking. I quaff water in long draughts, it tastes as sweet as only a cool drink can taste when one's throat is parched, and then I awake and have an actual desire to drink. The occasion for this dream is thirst, which I perceive when I awake. The wish to drink originates from this sensation, and the dream shows me this wish as fulfilled. It thereby serves a function the nature of which I soon guess. I sleep well, and am not accustomed to be awakened by a bodily need. If I succeed in assuaging my thirst by means of the dream that I am drinking, I need not wake up in order to satisfy it. It is thus a dream of convenience. The dream substitutes itself for action, as elsewhere in life. Unfortunately the need of water for quenching thirst cannot be satisfied with a dream, like my thirst for revenge upon Otto and Dr. M., but the intention is the same. This same dream recently appeared in modified form. On this occasion I became thirsty before going to bed, and emptied the glass of water which stood on the little chest next to my bed. Several hours later in the night came a new attack of thirst, accompanied by discomfort. In order to obtain water,
