Remorse over an alienated friend is signified in a dream of a cold radiator; regret is a futile waste of energy, but try to profit from the experience by thinking before you speak in the future. A hissing radiator in your dream is a sharp warning to stop considering a shady deal or furtive affair; if you give in to the temptation, you might mortgage your whole future. If your dream concerned an overheated car radiator, your love life needs unsnarling.
