We dream about many different things. When we go to sleep, our brain begins to take bits and pieces of memories and put them together into a dream. Some dreams are fun or silly, while others can be scary. Most dreams do not make a lot of sense, because our brain just took little pieces from a bunch of different memories. People do many things in their dreams that they really could or would never do, like fly or jump off a building, or swim and breathe under water.
Some people believe dreams all have a deep meaning.
Others think dreams are just jumbles of thoughts. There may be some truth to both ideas. Those who think dreams all have meaning, study the situations, places, people and objects in dreams, and then interpret them. They try to figure out what the dream meant to the dreamer. Some people believe dreams can predict the future, but studies have never proven that to be true, mainly because it is difficult to study dreams in a laboratory.
