Cover art for Blind lyrics by Placebo

I believe this song is about narcissistic couple when one(girl) is abuser and another is co-dependent narcissist craving her while understanding that something's wrong with her.

If I could tear you from the ceiling - the girl has a grandiose sense of self-worth And guarantee source divine - the boy understands that the only thing that will make her stay is an unlimited source of the narcissistic supply Rid you out of possessions fleeting - the boy sees what condition she is in, she's obsessed with hoarding some vain stuff (like golden watches or jewellery) Remain your funny valentine - this connotes Taste in men, it's a common for narcissist to abuse their victims with silent treatments on special days like St.Valentine or New Year's Eve

Don't go and leave me - narcs use abandonment as a weapon Please don't drive me blind - to drive blind - it's the kidnapper tactic to drive the victim around with a bag on the head, so she doesn't understand where she is and can't call for the help. In this context the girl confuses him about what state is their relationship is, and then leaves him

I know we're broken - the boy understands that they are both have a personality disorder there's reference to self-help books in Blue American, or take the cover of the Holocaust which is also about narcissism and oedipal complex,

and then he dreams of escape like (this is my very personal opinion) Marcello dreamt of escaping with Anna in The Conformist/Il conformista, or like Deckard and Rachael have escaped in the Blade Runner.

If I could tear you from the ceiling I know the best have tried - he understands that likely she has tried to be in relationship many times 'cause no normal person will tolerate the abuse and gaslighting, and there are a lot of others who were charmed with her

I'd fill your every breath with meaning And find the place we both could hide - theme of escape

Then comes the theme of blindness(which is also used in films I mentioned), and starting to see clearly, it's because those people are like the people in the Plato's cave, who are acting in the shadow play

And find a brand new way of seeing Your eyes forever glued to mine.

My Interpretation

A little correction - it's "I know YOU're broken", but IMHO it does not matter much.
