I've read many of the interpretation on line and I have to say that I think many people are living in the dog days ie:a state of naivete and innocence. Many other fans I have asked agree that the song is about an abusive relationship; heroin addiction. I don't believe "Flo" when she says its random lines strung together to create poetry. Every word and image were very thoughtfully chosen. When realize "horse" is one street term for heroine the chorus makes perfect sense. Run for help fast! The horses will destroy you. To use some of the imagery from the video you will ultimately be into hell.
