So it's 9:30pm on a cloudy night, you're in your bedroom or office, you are browsing your computer until you hear some shuffling, you ignore it at first, until it becomes more frequent and it grows louder and more frantic, you look around and find nothing, you resume browsing or fapping, whatever floats your boat.
You suddenly hear a window open accompanied by a sound of a sudden high pitched squeal.
You turn to the sound and you see this looking right at you.
What do you do/say/react?
