You're a deaf person as you were home. You see that the lights went on because of the volume you didn't know, but there was actually a person in here right when you were here alone. Since you were deaf you didn't notice that he was in the house. You felt a small presence behind you but thought it was just the wind

"How bad that you can't hear, huh ?"

He said behind you in a low voice, yet you didn't hear him
