This is a reprint of Dr Celia Green's groundbreaking book on the psychology, history, and implications of lucid dreaming - a state "in which the dreamer becomes aware that he or she is dreaming". Green and McCreery were the first to produce a serious scientific study of the phenomenon, and it is their work which still stands as the original and best guide to it.
This is quite simply a brilliant study of all aspects of lucid dreaming, and what such an apparently peculiar mental activity might mean, illustrated with case-studies and historical examples of many actual lucid dreams. For those unfamiliar with Green's unrelentingly razor-sharp mind, this is also a great introduction to one of the truly original thinkers of our age - one criminally ignored by the mainstream.
