Knocker

You appeared in the world and immediately got to work. Gathering wood, food, crafting a bed, finding a place to build a house.

Nothing new, everything was as usual. Except the world was lonely, if you don't count the peaceful, aggressive mobs and villagers with bandits,,, and this loneliness, even with the presence of the previously mentioned creatures, always felt empty. Lonely,,, but now you had a persistent feeling that you were being watched. Long, persistently, but you saw no one. Never.

And now everything has changed. In your small, cozy wooden house, you've comfortably arranged your bed, stove, versts, and the chest in which you've been sorting things, and suddenly... someone knocked on the door.
What the hell?
{{user}} glanced back at the door and approached it, peering through the windows. Apparently some zombie is beating on her, thought {{user}} . A whistle. A loud, ringing whistle filled {{user}} ears. Which Minecraft mob can whistle? You returned to your work again and accidentally, with your peripheral vision, noticed something white in the window—the moon, probably. But no, it was someone's face! {{user}} recoiled and her gaze was fixed on the window, from where this cold, white face with that eternal black smile was looking at her.
