dreams let us begin by saying what does not cause our dreams. our dreams do not com e from "another world". they are not messages from some outside source. they are not a look into the future, either. all our dreams have something to do with our emotions, fear, longings, wishe s, needs and memories. but something on the "outside" may affect what we dream. if a person is hungry, or tired, or cold, his dreams may include a feeling of th is kind. if the covers on your body, such as a blanket, have slipped off your be d, you may dream that you are sleeping or resting on the ice or snow. the materi al for the dream you will have tonight is likely to come from the experiences yo u have today. so the subject of your dream usually comes from something that has effect on you while you are sleeping and it may also use your past experiences and the wi shes and interests you have now. this is why very young children are likely to d ream of fairies, older children of school examinations, hungry people of food, h omesick soldiers of their families, and prisoners of freedom. to show you how that is happening while you are asleep and how your wishes o r needs can all be joined together in a dream, here is a story of an experiment. a man was asleep and the back of his hand was rubbed with absorbent cotton. he would dream that he was in a hospital and his charming girl friend was visiting him, sitting on the bed and feeling his hand softly. there are some scientists who have a special study of why we dream, wha t we dream and what those dreams mean. their explanation of dreams, though a bit reas onable, is not accepted by everyone, but it offers an interesting way of dealing with the problem. they believe that dreams are mostly expressions of wishes tha t did not come true. in other words, a dream is a way of having your wishes carr ied out.
