The ghost stories contribute to the horror as they are often tied to the house's past traumas. When we learn about the children ghosts and their possible fates, it makes the house seem like a place full of pain and suffering. This emotional aspect enhances the horror. Also, the faceless ghosts in the shadows make the viewers constantly on edge, as they could be anywhere. All these elements combined make the house a terrifying place and create a truly horrifying atmosphere in the story.
