Living Dead

How to kill people?
Is just a matter of putting something inside a head
And I'm not talking about a thing of steel
That explodes and burns
And drop you instantly to the floor and hurts
Is something crazy that they stuck inside you head
That gives you fear
So you don't know what you want or who you are
Once you feel it you're gone
Still exists, but already dead
Your turned (into) a living dead
