Why is it that when you awake to the world of realities you nearly always feel, sometimes very vividly, that the vanished dream has carried with it some enigma which you have failed to solve? You smile at the extravagance of your dream, and yet you feel that this tissue of absurdity contained some real idea, something that belongs to your true life⁠—something that exists, and has always existed, in your heart. You search your dream for some prophecy that you were expecting. It has left a deep impression upon you, joyful or cruel, but what it means, or what has been predicted to you in it, you can neither understand nor remember.
