The ability to think abstractly that flourishes during daydreams also has important social benefits. Mostly, what we daydream about is each other, as the mind retrieves memories, contemplates "what if" scenarios, and thinks about how it should behave in the future. In this sense, the content of daydreams often resembles a soap opera, with people reflecting on social interactions both real and make-believe. We can leave behind the world as it is and start imagining the world as it might be, if only we hadn't lost our temper, or had superpowers, or were sipping a daiquiri on a Caribbean beach. It is this ability to tune out the present moment and contemplate the make-believe that separates the human mind from every other.
