The Complete A to Z Dictionary of Dreams: Be Your Own Dream Expert by Ian Wallace is a comprehensive guide to understanding dream imagery, symbolism, and the possible connections between dreams and waking life. Published by Ebury/Vermilion in 2014, the book contains over 12,000 dream symbols and meanings and is structured in two main parts: an introduction to Wallace's approach to understanding dreams, followed by an extensive A–Z dream dictionary.

Wallace introduces his Dream Connection Process, which encourages readers to connect the images and symbols appearing in their dreams with situations, emotions, opportunities, and personal experiences in everyday life. The book also discusses fundamental questions such as what dreams are, why we dream, how to remember dreams, how dream symbols develop, and how dreams may reflect unconscious thoughts and feelings. Examples include common dreams about flying, falling, losing teeth, missing a bus, or being naked in public. With its extensive alphabetical reference section, the book works both as a general introduction to dream interpretation and as a practical reference for exploring individual dreams.
