Number one, the first places that fantasies come from is unfulfilled desire. What’s an unfulfilled desire that maybe you think about? It’s something that you haven’t experienced, but you long for it. You really want to experience that thing. Maybe it’s something that you have experienced, or are experiencing right now with some frequency, but it is not with the frequency you want. [Or maybe] it’s an unfulfilled desire that you have, and you’re longing to experience it, so you go to fantasy in your mind.
