How much is that doggie in the window?

In my dream, I was back in school (Oh no! I can't believe it! I'm back in school!) It was Home Room period (I think) where the teacher had the students sing. My brother (who's two years younger than I am) had just finished singing and soon it was my turn.

The teacher had me sing (of all things) a song about pets and I wondered what "pet" song I would sing. I thought about it for a moment and said, "Hey! We have a dog!" (Actually, we never had a pet dog.) The teacher nodded in assent and I started racking my brain for songs about dogs.

After what seemed like an eternity, I smiled sheepishly and admitted that I'm not very familiar with songs about animals. The teacher then gave me a song book and I quickly leafed through the pages for a song about dogs.

And then I woke up.

I'd bet Lamarck never saw this coming

So in my dream we have this aquarium at home. And there was this big fish swimming around in it. There was something crazy going on in that aquarium and I felt like the fish was going to want to leave it in some fashion as it tried to keep its head above water. And leave it did!

After a few minutes of staring at it, the fish began sprouting legs. Moments later, the fish turned into an iguana and promptly climbed out of the aquarium and onto a nearby shelf!

And once there, the iguana turned around and transformed into a four-inch...horse? (...complete with reins, saddles and everything)
