The original twilight zone in the 1960's was a mixture of science fiction, superstition, fantasy, horror, drama and suspense. It was a psychological thriller with a surprise ending. The unexpected twist was alarming and sometimes grim and ghastly, but it had a moral teaching. Listen to the introduction:
“There is a fifth dimension beyond that which is known to man. It is a dimension as vast as space and as timeless as infinity. It is the middle ground between light and shadow, between science and superstition and it lies between the pit of man's fears and the summit of his knowledge. This is the dimension of imagination. It is an area which we call the Twilight Zone.”
Twilight is the time between sunset and darkness and also the mental state between reality and fantasy. This is exactly our position today.
