I guess it's because I've just read a lot of novels from the twilight saga this past couple of days, but for some reason when I heard the song again it reminded me of. Err, silly as that sounds, romance between a human and a vampire! You know, lyrics like 'defenseless inside' and 'dried' made me think that, despite the vampire's massive physical strength, he/she is still defenseless inside -- has a vulnerable mind. And the 'so cold' bit could be the cold skin of vampires, something that doesn't scare the singer, because he keeps telling the vampire to touch him again and again. And, um, crowded streets would definitely run if a vampire walked into their midst -- even the ones that bragged about being able to defeat anything (hollow heroes) would run. But that is, of course, a very silly meaning! I just had to post it. *Lol*.
The other explanation seemed better!
