"No.
"You imagined them," breathed the doctor. "They aren't there. Not there at all. Can you hear me, Thompson?"
"Yes."
"Now forget all about your little green men. You can forget about them. You will forget about them." The doctor's voice was a monotone. "They ... never were there. You will never see them again. Never, Thompson. Never see them again. Never again. Thompson. Now go to sleep. You've been dreaming."
Thompson relaxed.
"Thompson?"
The sleeping man lay still, eyes shut, breathing even. The doctor exhaled softly.
"Why did you do that?" queried the nearest green man. "He's convinced. He'll never see us again."
"Naturally," said the doctor. He didn't even turn around. He got his spectacles out of his pocket and adjusted them on his nose. He turned to face the little green men.
