What are you?

[Verse 1:]
Your call brought me down here. It came from inside, and took over my mind. And all that's left behind is dust; an effigy of empathy and trust. How long have you been down here? Pulling the strings, mimicking shadows, now torn at the seems. So now I have to know:
[Chorus:] What are you? Why are you hiding in my mind? What are you? You are not of my kind. Mimicking, mimicking everything I wanted to see. (Mimicking, mimicking, mimicking, mimicking.) Mimicking, mimicking everything I hoped this would be. (Mimicking, mimicking, mimicking, mimicking.)
[Bridge:] Whose direction did I follow? What's the price and what's the cost? I fell for the trick and I've been swallowed whole, will I live eternally afraid and lost? I believed in all your lies, but now I know just what I saw. Bred to mimic, born to kill. My life was stolen by no flaw. You're the monster in the basement. You've been hiding in the dark. I just want to go home, but I fear I've gone too far
[Verse 2:] YOU HAVE STOLEN MY LIFE! YOU'VE TAKEN MY SOUL! I'M UNDER THE KNIFE, UNDER YOUR CONTROL! NOW I'M DEAD ON THE RUN! FROM FANTASY AND NO FUN! THE LIE IS COMING UNDONE, THE LIE IS COMING UNDONE! THROUGH TRIAL AND TURMOIL, I KEPT AN EYE ON THE SCREEN, BUT YOU CONTROLLED EVERY MOMENT IN YOUR PERFECT MACHINE! LOST IN A CAVE WITH NO EXIT; A MAZE WITH NO PRIZE! ALL THAT'S LEFT IS THE SIGHT OF YOUR TWO EVIL EYES!
[Chorus:] What are you? Why are you hiding in my mind? What are you? You are not of my kind. Mimicking, mimicking everything I wanted to see. (Mimicking, mimicking, mimicking, mimicking.) Mimicking, mimicking everything I hoped this would be. (Mimicking, mimicking, mimicking, mimicking.)
[Outro:] What are you? (Mimicking, mimicking.) Why are you hiding in my mind? (Mimicking, mimicking.) What are you? (Mimicking, mimicking.) You are not of my kind. (Mimicking, mimicking.) Mimicking, mimicking everything I hoped this would be-e-e-e-e-e-e
