The positive function of dreams is usually nothing more than a stimulus to the imagination. One can dream a lot without doing anything; one can even live in one’s dreams, enjoying oneself and truly feeling when dreaming. However, in the most common type of conscious dream, there is something that, if not exactly playful, is certainly free of the weight of real action. All this changes when the dream takes the form of a design, a purpose, which usually occurs when one gives up something for it. Here, the dream densifies, the dream already influences life and, to a certain extent, begins to materialize. It’s true, it’s true: it often remains unrealizable, or at least does not come true. That may not matter; the seriousness it takes on is enough to differentiate it from ordinary dreams and, above all, to decide.
