I walk through my neighborhood, but there's certain things off, like the sidewalks are either too wide or get randomly cut off by grass, and I reach my house. There's not much difference, except the doorknob is missing from the door. I knock on the door a few times, and no one answers, so I start walking away. Then, I "remember" a superstition saying to never knock on the door of an empty house (I can't find anything online saying that's true, so it was probably a false memory)
Then, this man comes out of the house across from me. He's wearing a brown suit or something, he looks slightly out of proportion, and he has no head. He starts running towards me. I scream, and I wake up.
