Meanings of Dreams

Why Do We Dream?
Nobody knows for certain why we dream. One of the first people to come close to a scientific explanation 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 vapours 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.
Science asks: Why Do We Dream?
Early in the 20th century the first scientific theories about sleep and dreams proposed that chemicals such as lactic acid, carbon dioxide and cholesterol, collected in the brain during the day. These were dissipated during sleep. In short, sleep and dreams were thought to be a function of the elimination process of the body.
Today some psychologists are reconsidering these initial ideas. Although Aristotle and others were clearly wrong about their science, they may have been correct in saying that dreams are a physiological process. Some of the latest theories propose that dreams are the body’s way of ‘rebooting’ the brain. Dreams dispose of memories that would otherwise clutter the mind with unnecessary remembered experiences. In particular they enable the emotions to become balanced. Dreams get rid of the junk and allow the brain’s complex chemistry to stabilise. Without dreams, we would simply overheat.
REM Sleep: A way to discover Why We Dream?
One of 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. In 1955, Eugene Aserinsky and Nathan Kleitman published a paper on these strange eye movements. 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 and both the penis in men and the clitoris in women become erect. 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.
How Often Do We Dream?
Most of us dream every 90 minutes and the longest dreams, lasting 30 to 45 minutes, occur in the morning. Studies have shown that half of us wake during REM sleep and recall our dreams but the rest wake during non-REM sleep and are less likely to recall a dream. This may account for why many people believe that they “never dream”. The truth is that we all dream- every night- but most of us forget we’ve been dreaming.
REMEMBERING DREAMS
Before we can work with our dreams, we firstly need to learn how to remember them. A simple technique is to set your alarm clock a little earlier than usual. This may interrupt a period of REM sleep and you are more likely to recall a dream. Some authorities claim that many people unconsciously wake themselves at a time when they are not dreaming, because they want to repress what their dreams are revealing. It has also been shown that you are more likely to remember dreams if you are keen to have them. The fact that you are reading this book will increase the likelihood that you will have more dreams- or so it seems. In reality, you are only becoming aware of the rich dream life you already have. The difference is that now you are learning to take notice and remember them.
Another technique is to drink a large glass of water before you go to bed. You’re likely to wake up during the night wanting the bathroom. By doing this you may interrupt a REM period and thereby recall a dream. I’ve tried the method and it works but apart from being uncomfortable, I invariably wake to find that I’ve been dreaming of trying to find a toilet!
THE SEASONS
Spring: To dream about spring is a sign of fortunate undertakings and cheerful companions.
Summer: Summer foretells joyous events and prosperity; denotes the maturity of ambitions and signals unbound satisfaction.
Autumn: Implies cycle of transformation and change of surroundings. Will experience many ups and downs.
Winter: In this case is a cycle of disintegration and rest. It foretells happiness and financial gains.
