my Aunt was spending a few nights at someone's house to do some work for them, and was sleeping in a room at the end of a hallway, just off to the left of the end. one night she woke to a girl crying and thought "oh [my kid] woke up again... wait. i left my kids with a babysitter and these people have no kids..." she looked at the open door and a girl walked past it, through the wall at the end, crying all the way. my Aunt was just like "ok, gonna stay in bed tonight 😱🤔"
