I'm at my parents'. In the bathroom, in the main part of the house, there is a skylight through which I see an alien spacecraft. It hovers down very close to the house, and then reaches out a robotic arm, which is uses to replace a similarly robotic-white-colored piece of some apparatus that is attached to the house just outside the skylight.

Frightened, I run to the living room to tell my parents. I saw it for myself. It was installing some part to spy on us, or the world!
