Ugh - that would make me completely flip out. One night, when I was living in Manhattan,
I had kept the window slightly ajar in my bedroom, which faced a fire escape. Dumb move. Note: my bed was right under the window. I slept like a baby, UNTIL something startled me, *shocked* me, is more like it. I felt some weight on my head - guess what? A giant mouse had jumped right on my head. I screamed and screamed and screamed! I'd never been so utterly repulsed, disgusted, grossed out, and terrified in all my life. I had to run after it with a broom - killed it with the handle, screaming and yelling at it the whole time. What a scene.
