Lyric discussion by mister care-too-much 

I feel like this is about an abusive relationship. "Because it's only water in your eyes / And it's only words out of my mouth" could be the abuser trying to minify and distance themself from their actions. "I know that you are hiding in there...Is it ok if I let you out?" - the abuser wonders if they can trust themself not to hurt the one they love.

Also, has anyone seen the video? Intense stuff.
