Brave new world: Imaginative fictions offer simulated safety and actual benefits.

Human engagement with imaginary worlds pervades history (e.g., Paleolithic cave paintings) and development (e.g., 18-month-olds pretend). In providing a safe environment, separate from the real world, fiction offers the opportunity for simulated exploration regardless of external circumstances. Thus, engagement with imaginary worlds in fiction may afford individuals opportunities to reap benefits and transfer these benefits back to the real world.
