Mouse = musculus = muscles. Not sure what that means.
Later, I dreamed that vampires were on the loose. Our next-door neighboor was sitting on his steps, in the very doorway a vampire had just passed through. He's Norwegian, we observed to each other. Those phlegmatic Norwegians. When we started to worry whether the neighbors had become vampires, I said, Well, they have that Norwegian temperament. They might be calm vampires. We peered through the curtained window of our kitchen door, across the alley to their house. Their door was open and the man and his wife were rolling around on a bed together. Then we realized there was also a vampire in the bed, with emaciated limbs and powdery, cracking skin. That was rather terrible.
Tracey Ullman's son turned into a vampire, too, but I'm afraid I can't remember much about that.
