"With four musical notes, you're traveling to a destination accessed by a door, unlocked with the key of imagination. Beyond it, is the discovery of another dimension as vast as space and as timeless as infinity. A dimension not only of sight and sound, but of mind. It is the middle ground between light and shadow, between science and superstition, and it lies between the pit of one's fears, the middle of one's desires and the summit of one's knowledge. This is the Fifth Dimension: A wondrous land of things and ideas, whose boundaries are only that of the imagination. It is an area which we call the Twilight Zone."
