The Head Trip: Adventures on the Wheel of Consciousness by Jeff Warren is an entrancing taxonomy of waking, sleeping and dreaming states of consciousness.
It is a book of psychology and neuroscience, and also of adventure, wherein the author not only comes to a new understanding of the relationship between the mind and the body,
but—perhaps mistakenly—comes to believe he possesses thrilling and unusual consciousness superpowers. The many figures, sequential panels and mechanical devices are
drawn by the author.
