C. G. Jung
"Dreams have roots that stretch deep into the unconscious. In Jung’s psychology these roots burrow through the personal unconscious, the collective unconscious and possibly even tap into the mysterious psychoid realm. Dreams provide the connecting thread between our past and our future. When we lose this important link, we become unmoored from our beginnings. But the beginning is critical. It is the first step in every life, every journey, which determines the direction of the path. It is for this reason that alchemists spent so much time meditating on the first step of their experiments, on what would constitute the first matter. They believed that everything required for the creation of the philosopher’s stone was contained in potential form within the prima materia, the first matter. In addition to rudimentary chemical substances, they used their dreams and visionary experiences to identify this vital material.
Modern science is now uncovering neurological relationships between dreams and the formation of permanent memories, which have been shown to be intimately bound together. Without dreams, permanent memories are not formed. Permanent memories represent the basic facts of who and what we are; they represent our beginning. Dreams therefore play a critical role in maintaining our identity. And yet, because dreams are elusive and alien to the world of reason, they are too often neglected, dismissed or sublimated into supercilious forms of entertainment. Consequently, we run the risk of neurosis and perhaps worse, a cognitively distorted history. No society can call itself great without having a dark, secret place where dreams are honored guests and we their attentive servants. If we listen carefully we may hear humanity’s voice, the universal sound and perhaps even the thoughts of God".
