It's about the girlfriend who left me last year. I tried to put all my anger in those words, even though I'm just as much to blame for the break-up. 'Soma' is based on the idea that a love relationship is almost the same as opium: it slowly puts you to sleep, it soothes you, and gives you the illusion of sureness and security. Very deceivable.
