All our dreams have something to do with our feelings, tears, longings, wishes, needs and memories. But something on the “outside” may affect   we dream. If a person is hungry     tired or cold, his dream may include a feeling of this kind. If the blanket on your body has slipped   your bed, you may dream that you are sleeping or resting on the ice or snow. So the subject of your dream usually comes from something that has effect   you while you are sleeping(feeling of cold, a noise, a discomfort, etc.) and it may also use your past experiences and the wishes and interests you have now.
   are some scientists who have made a special study of why we dream, what we dream and what those dreams mean. Their explanation of dreams, though a bit reasonable, is not accepted by everyone, it offers   interesting way of dealing with the problem. They believe that dreams are mostly expressions of wishes that did not come     . In    words, a dream is a way of having your wishes carried out.
