Dreams are but foam – a dismissive judgment on the fascinating imagery of our sleep, which has often been imparted to us as a cautionary tale since childhood. Schiller, on the other hand, considered dreams a gift from the gods, while Sigmund Freud recognized that dream interpretation is the royal road to understanding the unconscious in our inner lives. In fact, dreams often reveal, though not always in a straightforward manner, truths and unconscious knowledge of the dreamer. The author uncovers how to understand and utilize the language of dreams through classical dream theory and astonishing cases from psychotherapeutic practice. According to C. G. Jung, dreams provide memories, insights, and experiences; they awaken dormant aspects of the personality and reveal the unconscious in relationships, making it rare for anyone who does not let it displease them to neglect their dreams.
