Girl
Girl (aka "Virtual Girl") is about the commercialization of all things SEX, really: hollow gratification.
It's important to connect with your partner in more ways than just physically. Be present 100% and gain.
Kill
Kill (aka "Kill Me") speaks for the victims of "sex" crimes (rape is not
sex). While I haven't personally experienced such horrors, it's never set well with me that monsters evade justice for the misdeeds they commit on a daily basis... in fact, they're often part of the American "elite".
Dream (aka "In a Dream") is about suicide. Most of us struggle with thoughts of ending life from time to time. Sometimes randomly, other times: during intense moments of turmoil and pain. There is no shame in seeking help, end the stigma!
