Brindle the Paranormal hunter

I got home yesterday around 11pm and saw a fast moving shadow. I never thought about it but when I was looking at my physio schedule in my car I heard a knock on my window. No one was there. I looked at my backup camera and not a person was in site. I wasn't scared!
As soon as I went outside I started to get chills like someone was watching me. I ran right inside the house. Maybe I just watch too much paranormal shows but this is the third time I experience something so unusual.
Im not worried. My paranormal hunter Brindle will hopefully figure this one out.
