This book aims to present a study on the actuality and empirical value of Freuds dream theory, even if through the analysis of a specific part of it - the hypotheses about childrens dreams. It provides a systematic description of Freuds observations on child dreaming and presents the results obtained from four empirical studies on childrens dreams that the author conducted during the span of a decade. These studies (two conducted in school settings, one in a home setting, and one based on a questionnaire completed by parents) allow an empirical judgment on Freuds main hypotheses on child dreaming: the hypotheses on formal aspect of childrens dreams, the relationship between dream bizarreness and development of the superego functions, and the issue of wish-fulfilment dreams. The author concludes that it is possible to test empirically Freuds hypothesis on the early forms of dreaming and that this test is not irrelevant for an empirical judgment of certain more general statements of Freuds dream theory (e.g. the dream censorship hypothesis).
