Few of us realize how many states of consciousness we pass through on a regular basis. In this entertaining guide, Jeff Warren explores twelve distinct, natural states we can experience in a twenty-four-hour day, each offering its own kind of knowledge, insight, and adventure. The hypnagogic state, when our minds hover between waking and sleeping, can be a rich source of creativity and even compassion. The “watch,” an almost magical waking experience in the middle of the night, has been all but lost.From sleep laboratory to remote northern cabin, neurofeedback clinic to Buddhist retreat, Warren fearlessly tries them all. Along the way, he talks to neuroscientists, anthropologists, monks, and others who illuminate his stories with cutting-edge science and age-old wisdom.
