"IT's the GHOOOOST HOOOOUSE"
Houses that have been destroyed, demolished, or renovated sometimes become vengeful spirits and terrorize people.
Ghost House is a specific spectral house that chooses its victim and only appears for that person. Whenever the person points it out no one else sees it, then that person is stuck looking like a fool. Then after a while they're all like "IT's the GHOOOOST HOOOOUSE" and everyone laughs at them.
