- Reading Dream on (A) Dreams have fascinated people for centuries. You might be surprised to learn that everyone dreams for around two hours a night, although not everyone remembers their dreams. It's estimated that people will spend around six years of their life dreaming. But why? While scientists have come up with many theories, they haven't reached any definite conclusions yet. [g] What exactly are dreams?They are the images.ideas and feelings you have while you are sleeping. Generally people see their dreams, but some dreamers experience dreams using other senses. Blind people.for example, are more likely to have dreams that involve smell sound or taste, perhaps because they use these senses more in daily life. The majority of people dream in colour, but there are people who say they only ever dream in black and white. In one study,researchers found that people over the age of 55 said that around 25% of their dreams were in black and white. In contrast, the under 25s only dreamed in colour. It is thought that this could be because the older group all watched black and white TV as children, before colour TV was easily accessible. (c) Before considering why we dream, it's interesting to know when it happens. Most dreams take place during REM sleep. REM stands for 'rapid eye movement' and it's the stage of sleep where your eyes move below your eyelids, your brain is more active and your heart beats faster. The first REM stage of sleep tends to be around go minutes after falling asleep, and lasts about 10 minutes. During the night, REM periods of sleep last longer, the final one might be as long as an hour. REM sleep periods are important because the parts of the brain that are active then are responsible for memories - making and keeping them-as well as learning. Dreams that you have during REM sleep are more memorable and more vivid and you'll probably have about five dreams every night, which are between five and twenty minutes long. Although we also dream during non-REM sleep, people remember these dreams less frequently -50% of people woken in non-REM sleep report dreams compared to 80% in REM sleep. [d.Some of the most popular theories about why we dream are related to memory and emotions. One theory is that dreams enable us to process everything we have experienced during the day, so important information can be stored as long-term memories. A similar theory argues that after learning something new, particularly a new skill, when we sleep the memory is activated, which makes it stronger. Some of these activated memories are then seen as dreams. Curiously, there's another theory that says that dreaming is a way of allowing the brain to forget unnecessary information. There is strong evidence that dreams help us with our emotions .

If Some people believe that dreams are an important part of creativity - we don't talk about 'dreaming up' ideas for nothing. When we are asleep.our brains aren't limited by reality and may come up with solutions to problems or incredible new ideas. It's not only research that supports this theory, many people including inventors, scientists and song writers have been inspired by dreams Larry Page once dreamed that he downloaded the whole web onto some old computers which gave him the idea of creating a search engine.and Google was the result. The writer Stephen King dreamed the story of one his books, and the tune for one of the most famous songs in the world, Yesterday, came to Paul McCartney in a dream . These are just a few of hundreds of examples. Hone thing that fascinates researchers is that there are certain universal dreams. People all over the world of different nationalities, cultures and ages all share some dreams. The most common ones involve flying, falling, being chased or being unable to move. Other typical dreams are about arriving late for something or taking an exam where you don't know any answers. It's possible that these dreams help us with negative feelings such as fear. embarrassment or worry. Fortunately, there are some positive common dreams, too such as discovering a new room in a place you know well, coming across some money or enjoying some delicious food. GlIt seems that dreams and why we dream are still a mystery. For now, many experts agree that it is likely that dreams aren't just the result of one thing but are likely to happen for a combination of reasons. 11 Read the article Are the sentences True (T) or False (F)?
