By Victor Emil Freiherr von Gebsattel. Since Freud's foundational work on dreams, literature on dreams has grown tremendously, but the systematic processing of this wealth of information has not kept pace with the help of individual observations, interpretations, and theoretical approaches. What dream research has lacked throughout its development is the organizing power and the overarching perspective of a mind capable of synthesizing so many contents. Only with the present compendium has the work of many researchers over decades entered the stage of fruitful systematization. The work "The Science of Dreams: Results and Problems" claims to introduce the general foundations of dream theory. As the title suggests, it encompasses both retrospective and prospective aspects.
