Everyone can dream. Indeed, everyone does dream. Those who claim that they never dream at all actually dream just as frequently as the rest of us, through they may not remember anything about it. Even those of up who are perfectly aware of dreaming night after night very seldom remember those dreams in great detail but merely retain an untidy mixture of seemingly unrelated impressions. Dreams are not simply visual-we dream with all our senses,so that we appear experience sound, touch, smell, and taste.
One of the world's oldest known written documents is the Egyptian Book of Dreams. This volume is about five thousand years old, so you can see that dreams were believed to have a special significance even then. Many ancient civilisations believed that you should never wake a sleeping person as, during sleep, the soul had left the body and might not be able to return in time if the sleeper were suddenly awoken .
From ancient times to the present day , people have been making attempts to interpret dreams and to explain their significance. There are many books available on the subject of dream interpretation, although unfortunately there are almost as many meanings for a particular dream as there are books.
