We all daydream and yet the purpose of waking fantasy, or episodes of conscious and private fiction-making, has never been really clarified. Instead, mainstream psychology characterises the daydream as task-distracted mind wandering, which does little to explain why people engage in creating fictions of often unrealizable proportions regularly for themselves, at times incidentally and at other times deliberately. This work overturns, re-organises and redefines established concepts of the role of waking fantasy in human life. It shows how the purpose of all fantasy is to transform mood states into specific emotional responses, a feature apparent in daydreams, sexual fantasies and even unconscious fantasy structures. Understanding how feeling states motivate fantasy explains why we daydream at all, how repetitive daydreams and sexual fantasies develop to elicit reliable emotional reactions, and even how we at times use and appropriate published or released fictional works to propagate our own fantasies. Along the way, the work explores the relation of waking fantasy to some of our buying practices, attachments to objects in early childhood, preferred genres of fiction and cultural phenomena such as the worship of celebrities.

This book seeks to re-define the role of fantasy in human life by overturning mainstream psychology's understanding of daydreams as being task-distracted mind wandering by proposing that all waking fantasies function to transform mood states into specific emotional reactions.
