To give you a very specific kind of working idea of what we mean by “Twilight Zone”, you might say that a man is on top of a burning building. Now there are certain ways he can get off that building — he can use a fire escape, a ladder, he might even be picked up by a helicopter. But in the Twilight Zone, he flies.

This is the so-called dimension of imagination, a literary device known by the English writer Coleridge as the “willing suspension of disbelief”. The things you see, you know may not happen. But at the time you see them on this program, you’ll believe that they do happen. This is the Twilight Zone.
