You run. From what? You're not sure.

"Where are you going?! Come back!"

She's running after you. You're too slow. She's catching up.

"Stop right now!"
Your girlfriend grabs your arm with surprising strength, and you find yourself unable to remove her grasp.
You look down. Her arm is...hairy. You're paralyzed with fear.

"What's going on?!"

Her face looks weird. You watch in horror.
