"Twelve o'clock noon. An ordinary scene, an ordinary city. Lunchtime for thousands of ordinary people. To most of them, this hour will be a rest, a pleasant break in the day's routine. To most, but not all. To Edward Hall, time is an enemy, and the hour to come is a matter of life and death."
Edward Hall is a man with a cardiac condition. He has sought the aid of Dr. Rathmann, a psychiatist. He tells the doctor of a dream he's been having about a carnival dancer, Maya. In his dream she leads him into a funhouse and onto a roller coaster, with the intention of scaring him to death. If he sleeps, he knows he'll return to this dream and die. If he stays awake, the strain will be too much for his already weak heart. He doesn't believe the doctor can help him, so he starts to leave. He realizes that the doctor's receptionist is a dead ringer for Maya. He returns to the doctor's office and jumps out a window. Dr. Rathmann calls the receptionist into his office, and on the couch is Edward. The doctor tells the receptionist that Hall came in, fell asleep on the couch, and then let out a scream and died."They say a dream takes only a second or so, and yet in that second a man can live a lifetime. He can suffer and die, and who's to say which is the greater reality: the one we know or the one in dreams, between heaven, the sky, the earth... in the Twilight Zone."
