How does your song embody the theme "fight or flight"?
I have a little story in my mind. A character decides it wants to fly a plane, so it takes off into the sky above and flies through the clouds, enjoying the breath-taking views and the thrill of flying fast. But at one point it flies into storm clouds that try to crash it's plane, so it has to fight through them just to stay alive. It does exit the clouds afterwards and decides to land. It enjoyed it a lot, remembering what it has done from start to end.

Flight as in flying a plane (melodic DnB), Fight as in trying to fly through the storm clouds (electric guitars and the use of acoustic drums)
