The author focuses on some clinical implications of Bion's thought. He takes into particular consideration the great technical importance of Bion's concept of “waking dream thought”. He proposes some developments of Bion's thought as well. Psychoanalytic exercises like those suggested by Bion are presented along with clinical material in order to render the author's theoretical-technical ideas as clear as possible. Furthermore he deals with the fertile connection between Bion's theories and the field concept in psychoanalysis.
