I've heard the voices say many things that also make it harder to believe they're just in my head.
One night when I could hear a group of guys in a car driving to my house, I heard one of them say "he's fine with the fact that you broke into his house?"
At that point, I then heard the car turn around.

Since I've been hearing the voices, I've also heard people who have lived above us following me and my family throughout the house, even into the bathroom.
