The subject of this book is the study of dreaming from a specific point of view, which provides useful and enlightening results: the analysis of the complex patterns of links among the memory sources of dreams. The significance of these patterns is logical and emotional at the same time. This approach is interdisciplinary: it directly involves the fields of psychology, psychotherapy, linguistics, computer science, mathematics (graph theory, neural networks), history of psychology, literature, and motion pictures. However, no specific advanced expertise in any of these fields is required for understanding the various contents.

Galileo stated that, from the viewpoint of the Copernican System, the fall motion of a body towards the Earth center is uniform circular. He himself assessed this statement as “Bizzarria” (bizarreness). The book is dedicated to the study of this significant issue of Galileo’s physics.
