When people hold their breaths, it's mean they're expecting something happen. So this means as an advice that "don't expect, it will not happen"
You can’t touch me now there’s no feeling left If you think I’m coming back don’t hold your breath What you did to me boy I can’t forget If you think I’m coming back don’t hold your breath (Lyric Don't Hold Your Breath - Nicole Scherzinger)
