Let us begin by saying what does not cause our dreams. Our dreams do not come from "another world ". They are not messages from outside sources. They are not a look into the future, either.

All our dreams have something to do with our feelings, fears, longings, wishes, needs and memories. If a person is hungry, or tired, or cold, his dreams may include a feeling of this kind . If the covers on your body, such as a quilt or a blanket, have slipped off your bed, you may dream that you are sleeping on the ice or snow. The material for the dream you will have tonight is likely to come from the experience you have today.

So the subject of your dream usually comes from something that has an effect on you while you are sleeping (feeling of cold, discomfort, etc.) and it may also use your past experiences and the wishes and interests you have now. This is why children are likely to dream of fairies, older children of school examinations, hungry people of food, homesick soldiers of their families and prisoners of freedom.

To show you how this is happening while you are asleep and how your needs and wishes can all be joined together in a dream, here is the story of an experiment. A man was asleep and the back of his hand was rubbed with a piece of absorbed cotton. He would dream he was in hospital and his charming girlfriend was visiting him, sitting on the bed and feeling gently his hands.

There are some scientists who have made a special study of why we dream, what we dream and what those dreams mean. Their explanations of dreams, though a bit reasonable, are not accepted by everyone, but they offer an interesting approach to the problem. They believe that dreams are mostly expressions of wishes that do not come true. In other words, dreams are a way of having your wishes carried out.
