Quote by Dream / Morpheus (Season 1 Episode 1)

We begin in the waking world, which humanity insists on calling the real world as if your dreams have no effect upon the choices you make. You mortals go about your work, your loves, your wars, as if your waking lives are all that matter. But there is another life which awaits you when you close your eyes and enter my realm. For I am the King of Dreams and Nightmares. When the waking world leaves you wanting and weary, sleep brings you here to find freedom and adventure. To face your dreams and fantasies in Dreams and Nightmares that I create and which I must control lest they consume and destroy you. That is my purpose and my function. Or it was, until I left my kingdom to pursue a rogue Nightmare.
