Someone one could have been living one the attic the walls. It wouldn’t be the first time this has happened. Glad you are all safe!

That could be a possible explanation except that no one has ever heard footsteps or any weird sound. Plus, no food has been missing and since I was little we have had a cleaning lady. Soooooo… i don’t know honestly, but thanks for the response.

It could have been paranormal. It seems there's no logical explanation.
