Dreams are stories or pictures in your head when you are sleeping. Everybody dreams, even if they don't remember it afterwards. Dreams can help us think about things and help us feel better about ourselves and our lives. They help us figure out what we are thinking and feeling, even when we don't know it. Dreams can also help us learn more about the world around us. When you dream, your brain is sorting through all the thoughts and emotions you have during the day, and it helps you make sense of your life.
