The book’s first three chapters-by Sheehan and Robertson; Wagstaff; Council, Kirsch, and Grant – conclude that three different factors turn imagination into hypnosis. The next three chapters-by Lynn, Neufeld, Green, Rhue, and Sandberg; Rader, Kunzendorf, and Carrabino; and Barrett-explore the hypnotic and the clinical significance of absorption in imagination. Three subsequent chapters-by Coe; Gwynn and Spanos; and Gorassini-examine the role of compliance and imagination in various hypnotic phenomena. Pursuing the possibility that some hypnotic hallucinations are experienced differently from normal images, the following two chapters-by Perlini, Spanos, and Jones; and Kunzendorf and Boisvert-focus on negative hallucinating, which reportedly "blocks out" perceptual reality. The remaining three chapters-by Wallace and Turosky; Crawford; and Persinger-pursue other physiological differences, and possible physiological connections, between hypnosis and imagination.
