*Nightmares and Human Conflict* has several purposes. One of them naturally is to provide a general survey of the subject, to try to understand why these particularly disturbing dreams occur, and to set forth the various determinants of the overwhelming anxiety experienced in them. Since the nightmare is the principal condition in which dreaming and severe anxiety occur simultaneously, it affords an excellent opportunity to study the relationship between these two universal human phenomena. Finally, consideration is given to the relationship that nightmares may have to certain forms of creativity and to various pathological states, especially acute psychoses. This book is based primarily on my own clinical experiences, and actual case examples from child and adult patients in psychoanalysis and psychotherapy form the principal documentation. Other appropriate material from experimental research, literature, biography, and the psychopathology of daily experience of nonpatients has also been drawn upon.
