The author of this book is a follower of Stekel. He writes the book because he feels 'that the hitherto-existing books on dream interpretation are either too voluminous or too little instructive, or are out of date' (p. 1). He intends it to serve as a textbook on dream interpretation and for 'chiefly practical purposes' (p. 2). To judge from the glossary at the end of the book, it is meant primarily for the layman, since such words as cerebral, celibacy, defloration, introspection, phobia, are defined.
