Yes, for example there could be a magical unicorn at the door who doesn't like talking and who can't reach the doorbell and whose hooves are so tiny and soft that when he tries to knock, there's no sound.

Even though that's a possibility I would still just assume there's no one at the door, since I haven't seen this unicorn or heard him. I would probably just chill and not think about such things.

Poor little magical unicorn.

No shitstorm here, my friend, we simply don't give a fuck.
