What Are Dreams?Īlthough it is hard to define what a dream is, for the purpose of this article, we will define dreams as our thoughts during sleep that we recall when we wake up. Since we remember our dreams and then often forget them, what is their purpose? Why do we dream about the things we do? New research tools, particularly those that can be used to investigate the brain, are being used to answer these questions. She told me the dream with a laugh and then moved on with her day, ignoring the crazy animals and spaceships that entertained her in her sleep. At times, she and the animals would be out in space, but they also came back to earth. Although she knew she was in a spaceship in her dream, when telling me about the dream, she realized the spaceship was actually a washing machine. She was in a spaceship with some animals. When she was 8, my daughter told me about one of her dreams. Together, these studies show that dreams and sleep are important for performing well when we are awake. Or, when memories from the day are repeated in the brain during sleep, memories may get stronger. Strange combinations of ideas in our dreams may make us more creative and give us ideas that help us to solve problems.

Recent research into how the brain works helps us understand why we dream.
