I don't think it's inaccurate to say there are things, including some of our fears and fantasies, we know exist, but we avoid staring them in the face.  When we encounter them through an intermediary like our dreams or the playspace of a game, they grab hold of our attention.  Also, I just like letting simple things stimulate unexpected thoughts.

    I find Pac-Man interesting as abstract representations of fear and a power fantasy married in an addictive rhythm.  Pac-Man is literally trapped in a maze, outnumbered, and pursued.  Death is almost assured except for occasional opportunities to turn the tables on the enemies for a short time and chase them.  The enemies are ghosts, spirits of the dead coming to bring to an end my physically-bounded self, a moving ever-hungry mouth.  When I am powerful, they are ghosts, whispers of the once living scattering away because I no longer fear them and I am ALIVE.
