The song appears to refer to the political stance taken by the band in their earlier years, clearly stated by use of anti-war imagery in their music videos, during a time of rising military action.
As soon as the song starts, the screen turns black and white and hands pull Emily through her carpet.
When the first chorus begins, we see Jimmy Shaw playing the guitar covered in blood, while Emily sings.
Hands are reaching through the roof and walls, trying to grab her (a reference to the 1965 Roman Polanski film Repulsion).
During the bridge and final chorus, blood begins to leak from a lightbulb, a power socket, a television set, and other appliances (probably a reference to Sam Raimi's The Evil Dead).
