Friend or foe?

Friend or foe I cannot say
Does that finish my grip on your hand... no
You live at the edge
A heart made of stone sinks when it matters most
Dream like clouds in infinite form
I see you walking
Can I join you
No?
A setting sun doesn't breathe when interrogated
Lift the ban on oil spills
A rainbow left of center
I've never seen someone like you
Give me a drink from the river
My hand on your heart shows me the path to blinding light
