does anyone know what exactly takes over the house in House Taken Over? or is it just two old people going insane? I'm not sure and I have to write a paragraph on this, please answer soon

I think it's an unknown entity who's called "them" but it could just be the siblings going crazy.

Hope this helps and have a great day :)

And please mark me brainliest if you can :)

the words "strangest" and "unusual" suggest (:

what are you asking i dodnt know
