There is a danger in trying to portray what may or may not occur in a fourth or fifth dimension, simply because we have no idea what it may be like. In the pages of a book, it is possible because we get to use our imagination – anyone who has read Robert A. Heinlein’s excellent short story “And He Built a Crooked House” (you can read it here) will know what I mean. But trying to translate that to the small screen, especially in 1962, is a challenge.
The story of a girl who has fallen out of bed and through a portal in the wall of her bedroom to another dimension is done well enough. It is convenient that their friend Bill is a physicist, and his explanations throughout the episode are helpful in tracking the story. In the long run, the frantic (or less than expected) ministrations of the parents in locating their daughter and then dog seem to drain any real tension from the episode. I’m sure it looked better on paper in Richard Matheson’s original short story.
