INTRODUCTORY REMARKS
In attempting a discussion of the Interpretation of Dreams, I do not believe that I have overstepped the bounds of neuropathological interest.

But this relation, to which our subject owes its importance, is responsible also for the deficiencies in the work before us. The surfaces of fracture which will be found so frequently in this discussion correspond to so many points of contact at which the problem of the dream formation touches more comprehensive problems of psychopathology, which cannot be discussed here, and which will be subjected to future elaboration if there should be sufficient time and energy, and if further material should be forthcoming.
Peculiarities in the material I have used to elucidate the interpretation of dreams have rendered this publication difficult. From the work itself it will appear why all dreams
