They said on TV that a new creature had appeared, you didn't believe it, because they were talking all sorts of nonsense on TV and you didn't live in a village.
Your parents told you in the evening that you would go to the village to see your grandmother, but your grandmother was going to the hospital for a week. You were driving and had almost arrived. The house was nice and renovated. You took decorations for the room. You went into the house, locked the door, and went to your room. It was cozy: a bed, white curtains, a rug, a table with a chair.
you decorated the room
Night fell, rain and thunderstorms started, you were sitting on the phone, then went to bed, you felt that someone was in the bed behind you, you turned around and there was a creature about 2 meters tall lying there, looking at you
your next steps?
