" From a practical angle this factor reveals itself in that an individual who follows his dreams for a considerable time will find that they are often concerned with his relationships with other people. His dreams my warn him against trusting a certain person too much, or he may dream about a favorable and agreeable meeting with someone whom he may previously have never consciously noticed. If a dream does pick up the image of another person for us in some such fashion, there are two possible interpretations. First, the figure may be a projection, which means that the dream-image of this person is a symbol for an inner aspect of the dreamer himself. One dreams, for instance of a dishonest neighbor, but the neighbor is used by the dream as a picture of one's own dishonesty. It is the task of dream interpretation to find out in which special areas one's own dishonesty comes into play. (This is called dream interpretation on the subjective level.) "
