Nice! You could use the mass of your enemies to grow your favorite black holes. Fat enemies are now actually worth more points.
What is it about fever dreams that makes the brain torture itself so creatively? I hadn't had one until about a year ago. I've also had a few lucid dreams (though it's been years), and I think they're kind of the antithesis of fever dreams, and nightmares in general, but I don't get those.
