Each and every one of us loves to dream our wish. But nobody knows what a dream is and why we dream. Researchers after years of study stated that our dreams are what we believe or what we wish to happened in our life. They found that dreams have an effect on people's behavior; judgment as well as they might contain important hidden truths. To be more scientific about dreams, Dreams can be called as a succession of images, ideas, emotions and sensations occurring involuntarily in the mind during certain stages of sleep.
Some researches stated that dreams are a sequence of images or movies that our subconscious mind tells us. When we sleep, our subconscious doesn't need to battle with our conscious mind. Our emotional side is not challenged by our logic, so it's easy for our subconscious to break through barriers. But it isn't always easy to understand what it is trying to tell us. The subconscious relays messages in the form of dream symbols, or sometimes even bizarre dreams in which we are participants or observers. Explanations are many, but till now, nobody knows why we dream. The first person to give a scientific explanation of dream was the Greek philosopher Aristotle. At first, he spoke of the soul exercising special clairvoyant powers, in accord with its divine nature, when freed from the body's constraint in sleep. However, he was to conclude that the function of sleep and dreams was to dissipate the vapors that rose from the stomach after food. Similarly, for many centuries it was believed that blood rose to the brain and caused congestion there. Sleep enabled the blood to drain drained back into the rest of the body.
Researches carried out in the beginning of 20th century gave a new explanation to dreams. This new explanation stated that the chemicals such as lactic acid, carbon dioxide and cholesterol, collected in the brain during the day, are dissipated during the sleep time in the form of Dreams. Our brain empties these chemicals stored in this way. They are interesting, but there is no proof that can be given for this. The biggest breakthroughs in dream experimentation came in 1952 when a researcher noticed that the eyes of sleeping subjects would move beneath their closed eyelids. They named them "rapid eye movements" and called this phase of sleep REM periods. REM sleep (also now know as paradoxical sleep) occupies 20 per cent of your night's sleep and alternates with orthodox sleep about every 90 minutes.
It has been found that during REM sleep the flow of blood to the brain increases, as does the brain's temperature. REM sleep strengthens memory-traces although the release of growth hormones is less than during orthodox sleep. But most importantly, the brain shows a radical change in activity that can be measured on an electroencephalograph (EEG). If a person is awoken at this time, they usually remember vivid dreams. This discovery enabled scientists to tell how often we dream and by waking the subject during REM sleep they could guarantee there would be a dream to study.
While many theories have been proposed, no single consensus has emerged. Considering the enormous amount of time we spend in a dreaming state, the fact that researchers do not yet understand the purpose of dreams may seem baffling. However, it is important to consider that science is still unraveling the exact purpose and function of sleep itself. Until someone proves or disproves one of these theories, or poses an alternate one, we are left at square one. Our knowledge as to what causes us to dream is limited to the fact that we do dream, and that dreams occur during the REM phase of sleep. Sweet dreams!
