There are nuances of meaning for each of these. I don't know the song (context). But, I'll try to answer.
1. breathe someone back to life - to save someone, breathe life (soul) back into them
2. cold to the touch - it is cold; usually, a living person is dead when they are 'cold to the touch;' BUT, it also implies emotional separation - if a woman is cold to me, then she is (A) angry at me, or (B) she doesn't love/like me.
3. wind up dead - colloquial. 'To get yourself killed.' Usually a warning.
