Slamming doors
We mean, what else is there to say about this story, clearly someone in this family is just pulling a prank on this poor girl. Maybe they all don’t want to admit that they accidentally slammed the door in the middle of the night because they would get in trouble for making all the noise.
It is either that or the house is haunted and this girl has every right to never return there ever again. We think that is probably the best option for her, you never know when you might be there again and doors are slamming all over the place. Now that would really be scary.
