has brought to light if we reword our formula as follows: _The dream is the (disguised) fulfillment of a (suppressed, repressed) wish_. Now there still remain as a particular species of dreams with painful content, dreams of anxiety, the inclusion of which under dreams of wishing will find least acceptance with the uninitiated. But I can settle the problem of anxiety dreams in very short order; for what they may reveal is not a new aspect of the dream problem; it is a question in their case of understanding neurotic anxiety in general. The fear which we experience in the dream is only seemingly explained by the dream content. If we subject the content of the dream to analysis, we become aware that the dream fear is no more justified by the dream content than the fear in a phobia is justified by the idea upon which the phobia depends. For example, it is true that it is possible to fall out of a window, and that some care must be exercised when one is near a window, but it is inexplicable why the anxiety in the corresponding phobia is so great, and why it follows its victims to an extent so much greater than is warranted by its origin. The same explanation, then, which applies to the phobia applies also to the dream of anxiety. In both cases the anxiety is only superficially attached to the idea which accompanies it and comes from another source. On account of the intimate relation of dream fear to neurotic fear, discussion of the former obliges me to refer to the latter. In a little essay on "The Anxiety Neurosis,"[6] I maintained that neurotic fear has its origin in the sexual life, and corresponds to a libido which has been turned away from its object and has not succeeded in being applied. From this formula, which has since proved its validity more and more clearly, we may deduce the conclusion that the content of anxiety dreams is of a sexual nature, the libido belonging to which content has been transformed into fear.

[2] I myself regret the introduction of such passages from the psychopathology of hysteria, which, because of their fragmentary representation and of being torn from all connection with the subject, cannot have a very enlightening influence. If these passages are capable of throwing light upon the intimate relations between the dream and the psychoneuroses, they have served the purpose for which I have taken them up.

[4] It often happens that a dream is told incompletely, and that a recollection of the omitted portions appear only in the course of the analysis. These portions subsequently fitted in, regularly furnish the key to the interpretation. _Cf._ below, about forgetting in dreams.
