Sci Fi Story

I had the most unusual dream last night. I was in a walk-in cooler, (go figure that) there were all of these animals suspended from hooks from the ceiling. Don't worry they weren't real. They were giant, life size, brightly colored plastic animals. Their heads were large, dissected horizontally across the face so that the lower jaws moved. Their bodies swung from left to right andthe image reminded me of a childs crib. Over a loudspeaker a song tinkled loudly like the ice cream truck was coming. The animals all sung along with the bells, and as I walked through them they would slough off to the side then spring back behind me. The cooler seemed to go on forever...and then I woke up.

What in the world is that supposed to mean?
