"This is Miss Liz Powell. She's a professional dancer and she's in the hospital as a result of overwork and nervous fatigue. And at this moment we have just finished walking with her in a nightmare. In a moment she'll wake up and we'll remain at her side. The problem here is that both Miss Powell and you will reach a point where it might be difficult to decide which is reality and which is nightmare, a problem uncommon perhaps but rather peculiar to the Twilight Zone."
Miss Powell has a recurring nightmare about room 22 - a morgue, where a nurse opens the door and says, "Room for one more, honey." Her agent and doctor believe it's just a bad dream, and show her that the morgue nurse is not the same woman in her dreams. After being discharged she arrives at the airport, and finds that her flight number is 22. When she starts to board, a stewardess, the same woman in her dreams, says, "Room for one more, honey." She runs from the plane, back into the airport. The planes leaves, and explodes on take-off."Miss Elizabeth Powell, professional dancer. Hospital diagnosis: acute anxiety brought on by overwork and fatigue. Prognosis: with rest and care, she'll probably recover. But the cure to some nightmares is not to be found in known medical journals. You look for it under 'potions for bad dreams' - to be found in the Twilight Zone."
