Another Zombie Dream?

I don't even like Zombies...but I dream about them all the time. I'm not sure why. I don't find them any more frightening than other antagonistic, fictional creatures...but for some reason I have about one zombie dream per month. I also repeatedly dream about shoes...but that makes sense because shoes are a significant part of my reality.

In this week's zombie dream, I was not being chased by a zombie or group of zombies as usual. This time...I was the zombie. I was hideous. When I looked at myself in the mirror, my heart sank. What to do as a zombie? 

To make matters worse, I was at my parents' house where a very prestigious social event was being held. I resolved to somehow quietly leave the party without trying to eat anyone or without being seen...particularly by my mother, whose heart I knew would break if she were to discover that her daughter had transformed into such a hellish, half-dead thing. 

I made a break for the front door. My only mistake was glancing behind me as I reached for the doorknob. My mother was passing through the hallway as our eyes met. No! As I opened the door...I mouthed in slow motion..."I'mmmmm sorrrrrrry..." and I left...forever. Tragic.

Any interpretations?
