I also claim that studies of relaxed waking cognition, such as daydreams and passing thoughts, allow us to theorize about dreams on the basis of new ideas in cognitive psychology. At the most general level, dreams reveal our self-conceptions and our emotional preoccupations, and they tend to be more continuous with our waking thoughts and concerns than we generally realize.Both the accuracy and readability of this book were improved immeasurably thanks to an extremely careful and thoughtful reading of the first draft by one of the leading experts on dream content, Deirdre Barrett of Harvard University Medical School. I am deeply grateful for her time and effort. I also want to thank David Foulkes, the preeminent laboratory investigator of dreams for the past 30 years, for his very helpful and reassuring substantive comments on the second draft of the manuscript, and Richard L. Zweigenhaft, my longtime co-author on social psychology topics, for his frank and useful editorial suggestions on the second draft. My thanks, also, to my colleague Dane Archer in the Department of Sociology at the University of California, Santa Cruz, for advice on statistical questions, and to Mark Mizruchi of the Department of Sociology at the University of Michigan for his important corrections to my statistical appendix. Further thanks go to my colleague Daniel Guevara of the Department of Philosophy at the University of California, Santa Cruz, for his thoughtful comments on what philosophers say about the meaning of "meaning."The help of one of my former students, Adam Schneider, was essential to me in the final stages of the manuscript. He mastered the coding system and did creative work on three final analyses that added greatly to the argument. He utilized his outstanding computer skills to improve the accuracy of the tables and to check many previous calculations. He also caught many errors in his careful proofreading of the manuscript.
