I think this song means a girl, alone, living in a house that's old, but she calls it home. At a fast pace, she finds out that it's beens takin' over, by evil clowns. It used to be fun to live here, when her parents were still around. Now she has to burn it down, and run away, and find a house that is luxurious fun, modern style. A decent place to live, at the most.
