Faces- A Short Novel

Its been 5 days since I bought the house. I am typing this from my bedroom. There are five people staring at my bedroom window. They do nothing but just stand, and stare at the window. But when I open the door, they disappear. They still haven't moved. My phone camera shows an empty lawn. Every morning they disappear. I don't know what to do. I can't tell this to anyone. I am scared.
