Without a capacity for visual imagination, people would barely be able to think. Even when asleep, visual representations of the universe remain active in the brain. Children do not have the neural capacity to easily separate fact from fantasy, however, and so form beliefs that blur the bovundaries of reality. For example, they easily believe their nightmares are real. Adults,kon the other hand, have advanced neural processes to help them analyze perceptual discrepancies.
