When I read the phrase "I'm in my mind about something," an image popped in my head. I am sitting on my own brain in the classical Rodan thinker pose.
Personally, when my Internet goes out, I freak. "My connection goes to death," brought up the image of the Grim Reaper stabbing my computer to death with a sword.
I would make sure not to go overboard with the use of colorful, but unusual phrases so that others do think it was intentional and not because of language barriers.
