"Look at your ship, Harvey. It's old. It is very old. I'm going to tell you something. Something you already know, but won't admit to yourself...."
A frightened look appeared in Harvey's eyes.
"Well, go on. Tell me," he shouted impatiently, fearfully.
"After your ship left Earth, Harvey, it jumped the Light Barrier. But you and the others hadn't counted on the forces involved; everything but the man was designed to take that jump. You never came out of Overdrive, Harvey. You're still in that ship, and you'll never wake up!" She laughed/cried at Harvey's twisted face.
"You're crazy!" he roared hoarsely. "You're crazy! I remember! I know where I am, and how to get back!"
"Take a look around you, Harvey Crane," Dana laughed at him hysterically. "Do you think a world such as this could ever really exist?
"All this, Harvey," she gestured at the chunk of land, the Castle, and the moons—"They're just symbols. This island: your mind; the world edge is the end of Reality. Out there, the moons—they are insanity."
"But you wanted me to stay here. Why did you change your mind?" He stared at her accusingly.
"If you wish, you can ascribe motives to my actions," Dana said tiredly. "But they are your motives, not mine. Harvey, I'm just 'real' in your imagination. In Reality—the only Reality—I'm back on Earth, waiting. Harvey ... go back. I want you so!"
Harvey stared at her, incredulous. "But you. Who are you?" he blurted.
