Cartoons aren't supposed to mesh

This is freaky. I know I've been on a couple of school field trips with my baby sister but this dream felt so real. We were leaving a hotel that her choir kids were staying in and unbelievibly there was stuff of theirs all over the place. Like they really didn't know how to pick up and get ready to leave. I was leaning against a railing and knocked a pile of shirts off to the ground floor level leaving one of Jessi's schoolmates looking at me like "why'd you do that?" I remember looking for my sandles and the room me and my sister shared was strangely already occupied by another person (who was in the shower!). I'm not sure that works in the real world that quickly, but I never found my shoes because Jess looked out of the front window and said "the buses are already leaving" I had to wonder how and why because it seemed like they were missing a number of people. In the lobby we are looking around and we hear this singing. From the sides of the building pop out these muppet babies singing a song about moving and hats. And anything they touched turned into a moving/operating vehical. So maybe we didn't miss our ride home after all. I still have no idea where all this came from though.
