It’s a bit weak on substance, but then it would be, given that there’s no real scientific understanding of dreams, other than knowing that everyone has them and they seem to be important to brain functioning.  The book shares some of the ancient beliefs different cultures held about dreams, dream theories developed by famous psychologists 100 years ago or more, and some common themes that seem to pop up in many people’s dreams with theories about what they may signify.  It offers an idea for creating a dream journal to help readers remember and ponder their dreams.  The basic take-away from the book is that it’s fun to think about and everyone can decide for themselves what they think their own dreams might mean to them.
