When Brains Dream

Brilliant explanation of almost anything you could ask about dreaming as well as many related functions of the brain.

A thorough explanation of dream functions with proper references and mentions of alternative explanations along the way.
I specially liked the mature non-arrogant scientific position of being (and remaining) open to possibilities beyond current established facts regarding sleep. As the book mentions many discoveries seemed unreasonable at their time and later on proved to be correct and scientific. Remain open minded, but skeptic enough that your brain won't fall out!
