Lady's Head on Dog's Rear

Last night I dreamt I lived in a house with several friends from high school. The house needed a dog, I decided. The folks at the Humane Society kept trying to push this one dog on me. This dog was some kind of yellow lab, I guess, really quite cute with sad eyes. But, a woman's head was growing out of its butt. I mean, from where its tail should have been, grew a woman's head and a pair of human hands affixed to her neck. Also, she had a really bad haircut. Shoulder length, feathery. She wore no particular expression.

I felt sorry for both the dog and the woman, and took the thing back to the high school friend house. My housemates weren't too cool with the new pet; I grew fond of it/her.

The doorbell rang. The dog with lady's head growing from ass ran to the door and barked. Whoever was at the door--I didn't get a good look--was plenty disturbed and ran off. And suddenly I realized this dog/lady's head was a bad idea, fracturing my affection. I still felt sorry for the dog, but the expressionless ladyhead with limp hands, well, I wanted to kick her face. I wanted to take the pet back to the Humane Society, but I knew they would euthanize it, and in this state of ambivalence I awoke.

So, what does this mean? Besides the fact that I drank too much last night?
