Do i have a poltergeist?

Can someone explain this screenshot?

This is the 2nd time that specific wall has taken dmg. First time the stonewall infront of it was damaged by 25%, so i fixed it,and the brickwall. Now the brickwall is damaged 25%. But there are no scents, and it is within my village claim. So how on earth does it get damaged? Maybe a ghost?
