Poetic technique for taking a usually comforting thing in a scary context?
I was wondering what the name of the poetic technique was, where one takes something which is usually light, comforting and playful and takes into a chilling context.
Dolls sometimes are programmed to say
"Take me with you! We'll have fun."
But if we take this into the context of a broken doll in a pile of rubble, the "Take me with you! We'll have fun." suddenly seems like a plea for help.
Is there a name for the poetic technique of taking something with positive connotations and changing it such that it is chilling, like above?
