You are going to create some strange metaphors. and similes.
Brainstorm a list of abstract concepts (e.g. justice, racism, wisdom, compassion) or emotions (e.g. love, hate, jealousy, despair, grief, happiness).
Brainstorm a second list of concrete nouns or proper nouns (garage, dog, moonlight, engine, etc.)
Take a word from each list and put together with one of these two phrases:
Metaphors: [abstract concept} is a [concrete noun}
Similes: [abstract concept] is like a [concrete noun]
Take some risks and make the comparison as unexpected as possible.
Example: justice and rusted out old car
Add an additional line to your phrase that elaborates or explains the metaphor or simile.
Love is like a hurricane. It hits you unexpectedly. You are lulled by the calm at the center of it. Then you are devastated when it leaves.
Loneliness is a a rickety old green chair in a a corner of a dark room. Everyone knows it is there collecting dust. No one thinks of taking it out in the sunlight to fix it up, give it new life.
If you want to create a poem out of one of your metaphors or similes, try using a list poem format or try using an extended metaphor where you expand on your initial idea into a full story.
Here are two example poems:
Heart by Dorianne Laux,
Broken Promises by David Kirby
