This book explains many points of view on interpreting dreams, but only gives the big picture, not getting into too much detail. It's a great introduction to the subject, but not for use afterward on a daily basis. Also disappointing, it does not contain a dictionary of symbols and/or typical sightings in dreams. I guess they expect you to buy one. In that case, it should not be called "Complete" ... there are many more books I'd rather have on hand for reference.
I've read a lot on dreams. This book is by far the most comprehensive and easy to read. It's not goofy or too wedded to any one way of looking at dreams. The writing is really lively and humerous. And there is a lot of well-researched information, especially on the science of sleep. I'd say: buy this one!
