Synopsis

A very busy office worker,  not so busy daydreaming at work.  Her daydream leads her to believe that she is walking down, what appears to be a very long corridor.  She then approches the door at the end of the corridor.  She appears very anxious to open the door, so she opens the door and goes in.  She is greeted with a simple " Hello" and she begins to ask questions to which the response is a simple imitation of knocking three times on an imaginary door.  She then awakes from the daydream only to hear three knocks at her door.
