globe-shaking mystery—the fabulous Room of The Dreaming. Feeling states came at him, intangible, but to his trained senses, love. Since this place had been designed to excite the senses of both "Is the mighty human wanting liquor, a woman or dreams?" His voice "I'll have a tarmur to start," Johnson said. "How are the dreams tonight?" "Ze vill be the most wonserful of all sonight. The great Unger hisself will be here to do ze dreaming. There is no ozzer one who has quite his touch at dreaming, mighty one." The headwaiter spread his hands in a gesture indicating ecstasy. "It is my great regret that I must do ze work tonight instead of being wiz ze dreamers. Ah, ze great Unger hisself!" The headwaiter kissed the tips of his fingers. the dreaming commence?" admiring the slow rise of the tiny golden bubbles in it. To him, watching the bubbles rise was perhaps more important than drinking "I am very knowing," the girl said, smiling. "Are you sufficiently knowing to be here?" "Yes." "The reservations for ze dreaming, great one?" The headwaiter was bowing and scraping in front of him. "The great one has decided, yes?" "The dreaming!" Vee Vee looked suddenly alert. "Of course. We must see the dreaming. Everyone wants to see the dreaming. We will go, won't we were blended, but one aroma was prominent among them, the sweet, cloying, soul-stirring perfume of the Dreamer. In the suddenly hushed place little sounds began to appear as Venusians and humans began to shift their feet and their bodies in anticipation of what was to happen. "And you're the first woman who ever tried it on me." "But—" "Shall we go watch the dreaming?" He took the arm that still hung limp at her side and tucked it into his elbow. Moving toward the open door that led to the Room of the Dreaming, face was writhing in apprehensive agony and he was making warning signs. Johnson ignored them. With Vee Vee's fingers lightly patting his arm, they moved into the Room of the Dreaming. II the room was in darkness, a fit hiding place for ghosts or Venusian werewolves. Pillows and a thick rug covered the circling ramps. The soul-quickening Perfume of the Dreamer was stronger here. The accustomed to it, they began to detect rhythms and melodies that human minds had not known existed. The room was pleasantly cool but it had would have the feel of dampness in its dreaming rooms. The music playing strange harmonies in his ears, the perfume sending Dreamer. He suspected that other forces, unknown to him, were catching hold of his senses. He had been in dreaming rooms many times before but he had not grown accustomed to them. He wondered if any human ever "Do you feel it, darling?" "Yes." "What is it?" "How would I know?" "And how would I make certain you were Johnny Johnson, except by seeing True, the person they knocked unconscious would be all right the next illumination on the mat and the headrest at the bottom of the room. The curtain rose. passed through the audience. Unger bowed again. He stretched himself flat on the mat, adjusted the rest to support his head, and apparently went to sleep. Johnson saw the Dreamer's eyes close, watched the chest take on the even, regular rhythm of sleep. The music changed, a slow dreamy tempo crept into it. Vee Vee's fingers to take care of herself, and handle anyone around her. Now she was suddenly uncertain, suddenly scared. In the Room of the Dreaming, she had suddenly become a frightened child looking for protection. "Haven't you ever seen this before?" he whispered. "N—o." She shivered again. "Oh, Johnny...." Under the circle of light pouring down from the ceiling, the Dreamer lay motionless. Johnson found himself with the tendency to hold his breath. He was waiting, waiting, waiting—for what? The whole situation Rooms of the Dreamers. Certainly Martin thought so. And Johnson himself going.... Some of them were already gone. This was an old experience to them. They went rapidly. Humans went more slowly. The Venusian watchers had relaxed. They looked as if they were asleep, perhaps in a hypnotic trance, lulled into this state by the music and the perfume, and by something else. It was this something else that sent Johnson's thoughts pounding. The Venusians were like opium smokers. But he was not smoking opium. He was not in a hypnotic trance. He was wide awake and very much alert. He was ... watching a space ship float in an endless void . his vision, out of nowhere, out of nothingness. The room, the Dreamer, the sound of the music, the sweetness of the perfume, Vee Vee and this night, to the Dream Room of a Venusian tavern. The vision of the space ship floating in the void entranced and he was making contact with a vision that belonged to time. at Unger, dreaming on the mat under the spot. "The space ship!" "No. No." She seemed startled and a little terrified and half asleep. "I ... I was watching something else. When you moved I broke contact with my dream." "Your dream?" He asked a question but she did not answer it. "Sit down, darling, The vision would not come. Somehow he had the impression that the whirring sound which kept intruding into his consciousness was stopping the vision. So far as he could tell, he was the only one present who was not dreaming, who was not in a state of trance. His gaze went to Unger, the Dreamer.... Cold flowed over him. "This is it!" a voice whispered in his mind. "This is what you came to "This is another damned vision!" the second voice said. "This ... this is something that is not real, that is not possible! No Venusian Dreamer, and no one else, can levitate, can defy the laws of gravity, can float upward toward the ceiling. Your damned eyes are tricking you!" "We are not tricking you!" the eyes hotly insisted. "It is happening. We are seeing it. We are reporting accurately to you. That Venusian Buddha is levitating. We, your eyes, do not lie to you!" "You lied about the space ship!" the second voice said. "We did not lie about the space ship!" the eyes insisted. "When our him what they were doing. These were voices out of his training days when he had learned the names of these functions and how to use them. "Be quiet!" he said roughly. The little voices seemed to blend into a single chorus. "Action, Master! Do something." "Quiet!" Johnson ordered. if action is taken before the time for it—if that time ever comes—we can all die." "Die?" the chorus quavered. "Yes," Johnson said. "Now be quiet. When the time goes we will all go together." The chorus went into muted silence. But just under the threshold the little voices were a multitude of tiny fretful pressures. "I hear a whirring sound," his ears reported. "Please!" Johnson said. In the front of the room Unger floated ten feet above the floor. "Master, we are not lying!" his eyes repeated. "I sweat...." his skin began. "Watch Unger!" Johnson said. The Dreamer floated. If wires suspended him, Johnson could not see them. If any known force lifted him, Johnson could not detect that body-jarring thud, the Dreamer fell. Hard. There was a split second of startled silence in the Dreaming Room. The silence went. Voices came. "Who did that?" "What happened?" "That human hidden there did it! He broke the Dreaming!" Anger marked the voices. Although the language was Venusian, Johnson got most of the if some pleasant dream had been interrupted.
