Originally published in 1973, to this day "Dreams and Nightmares" remains the only book of Gestalt therapy transcriptions that includes ongoing commentary by the therapist. Jack Downing, one of the United States's leading gestalt therapy trainers, reviewed the session transcripts and frequently inserted detailed comments on the reasons he chose one type of intervention instead of another or why he used a particular Gestalt experiment as it relates to both the level of client self-awareness and Downing's particular experience with the person in the "hot seat." Because of the book's unique structure, it is one of the best teaching tools available for the famous Gestalt therapy dream work brought to the world's attention by Frederick Perls and Jack Downing in the late 60s and early 70s.
