Book excerpt: This unique book, incorporating both theory and practice, provides an invaluable guide to the assessment of dreams in transactional analysis (TA). Grounded in the latest neuroscientific research, it offers both neophyte and experienced TA practitioners a pathway to incorporate a client’s dreams within individual and group therapy, exploring key issues including trauma, dissociation and nightmares, dreams of change and transformation, dreams of healing, and transference and countertransference in dreams. It will support therapists through the very first steps toward the analysis of more complex interpersonal dynamics and dream analysis in a group setting. Also discussing the direction of future research in the area, as well as an overview of an experiment on dream analysis during the recent pandemic, this will be key reading for anyone working in the field.
