Why do we dream ?

Initially this book does not ask, how do we interpret dreams, but it does ask, why do we dream. It is Scientific psychology.
There has been many theories, why we dream, but they all seem to lack something. The book develop a new theory based on the nature of dreams, and their properties.
The theory is supported by dreamexamples. We see how you can realize in dreams, and how it contains emotions, that are clearified in the visual, where you see clearly. Dreams are compared to a magnifying glass, where you spot the World.
The author is a Danish licensed psychologist
