And yet?

The dials. Larger? By a fraction? And the tiny gleaming arrows of the meters. Barely longer? And the marks on the dials and meters? One extra each, very faintly, like a piece of hair.

He was very still for a long moment. Then he moved around the foot of his own sleeping tube, pushed between the two and stood at the head of the other one.

He checked its dials and meters. They were as they had been for many years. He stepped back to the panel of his own and pressed a button. As the glistening metal top rose, silently, he ran his hand around the yawning interior, felt the downy softness and the body-like warmth. Then his hand touched a pliable metal plate. That should not be there. He stood back, remembering the workmen who had come into the house that morning for the routine checkup of the tubes. His wife had already left for work and he had just stepped through the door when they had met him in the corridor. They had gone on into the rooms and he had sensed vaguely that something was wrong. Then he had put the feeling out of his mind and gone to his work.

Now suddenly, he turned to the illuminated four inch square panel above the door, read April 15, 2563. The workmen had checked a day early. He frowned. Either the Superfather had ordered the machine changed, which was highly improbable, because every object in the city was standardized and any change would upset the established order, or the workmen were tied up with the man who had given him the different dream cards.... In any event he had to sleep in the tube that night and he definitely wanted to dream the dreams on the cards he had just gotten from the man on the corner.

He dropped the cards into the slot at the top of the panel, climbed into the tube and pressed a button. The top closed over him, like a hand. He lay still, feeling the warm clasp wash over his body. There was darkness and silence and a cool motion of antiseptic air. He could try the first dream. If it wasn't right, he could shut it off and sleep without dreams.

He pressed another button.

Silence.

The sound of his regular breathing.

Then a sighing came into his mind, and a green haze. The sighing became a soft breeze; the green, tree-covered hills rolling off to the horizon. He relaxed, aware in a fading, sinking part of his consciousness that the machine worked as usual. He would dream and wait and hope....
