I was drawn to this book because of my desire to explore both the left and right brain information about dreams.
There was quiet a bit of history, which I thoroughly enjoyed, from the Upanishad's to Jung. I especially appreciated the deeper understanding of Freud's vs. Jung's take on dream study, and resonated with Jung's sentiment of "The manifest dream picture is the dream itself and contains the whole meaning of the dream."
Being in the health care field I loved the emphasis on how healthy, essential and fundamental dreams are, as well as the theories presented to suggest the pivotal nature of dreams, in regard to our evolution. Also, the neurophysiology and progressive biochemical changes that happen from the womb until old age captured my attention. Learning about fatal familial insomnia (FFI) was fascinating and something I don't wish on anyone!
"Manipulating dream content" was brought up and some experiments documented. It was a nice balance to other books that I also enjoy tremendously, but which are far more anecdotal accounts of controlling or becoming lucid in the dream.
Debunking the myth that the presence or absence of rapid eye movement (REM) dictated whether or not one was dreaming was interesting, although I'll still make up stories about what my dogs may be dreaming when I see them moving all around in their sleep. And, I'll always look favorably upon a book that supports my sleeping late in the morning...
Overall I highly recommend this book for those leaning toward the science of oneironautics, and not those who live more in their right brains. I'm not sure how much of the science was new, as the subtitle suggests, but it is certainly a compilation chock full of really great information. It will remain on my shelf as a reference for my own explorations, when I need to be in my left brain.
