It was a night like any other, the kind where the world seemed to blend together into a haze of forgetting and the glimmering shadows of memory threatened to consume all in their path. Lena sat at her desk, staring blankly into space as she tried to make sense of the day's events. She had always been one for reflection, but tonight it seemed especially necessary, a chance to catch up on everything and sort out whatever had become jumbled in her mind. As she sat there, lost in thought, the doorbell rang. Lena sighed and got up to answer it, hoping that whoever it was wouldn't keep her too long. She had work to do, after all, not the least of which was getting her head around what exactly had happened to her and why she felt so out of sorts.
