Humans of reddit, what was the weirdest/most paranormal way you have seen a pet/animal act?

My husband’s dog always goes to the window and growls whenever someone walks by our house, even if they’re just walking on the sidewalk. But one time, she was just sitting in the middle of the room and started growling for no reason. We looked out the window and saw a man walking down the street wearing all black, with a black ski mask over his face. We called the police and they said they would send someone by, but no one ever came.
