Dreaming is believing, claim researchers of a new study, who found that dreams have an effect on people's behavior, judgment as well as they might contain important hidden truths. Psychologists' interpretations of the meaning of dreams vary widely. But findings show that people believe their dreams provide meaningful insight into themselves and their world. 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.

When we sleep, we lose consciousness of ourselves. We do not know what happens to us or even our body. But our subconscious mind still keeps on working. Depending upon our desires, thoughts and events, we see them as dreams. Thus, your mind works in such a way that it fulfils whatever you desire. When some people agree with this, other just skips off the subconscious mind and gives explanation in another way. 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.

In the beginning of 20th Century, scientific theories about dreams 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. That means dreams are the elimination of these chemicals from the brain. 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.

During REM sleep the flow of blood to the brain increases, as does the brain's temperature. REM sleep helps to strengthen memory-traces although the release of growth hormones is less than during orthodox sleep. But the point that is to be noted is that 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

One of the best ways in which your subconscious mind attains your attention is through Dreams. Many people get psychic impressions from their dreams. Others may only dream when being given an alert about a situation. Some people think they never dream. They do, but probably can't remember. In some dreams, our friends and family members may make an appearance. Even loved ones who have passed on can show up from time to time to say hello. Dreams are all in the same way. Listen to them and cherish any little messages they send your way.
