"There's someone in my head, but it's not me"

This quote from Pink Floyd's tune "Brain Damage" is an effective metaphor for mental illness. It speaks to the feeling of being overwhelmed by one's own ideas and feelings, and the sense of being out of control. The concept of someone else being in one's head suggests that the person is not in control of their own ideas and feelings, and that they are being influenced by an outdoors force. This could be analyzed as a metaphor for anxiety, anxiety, or any other mental health problem. It might likewise be translated as a metaphor for addiction, as the person is not in control of their own behavior and is being affected by an outdoors force. The quote speaks with the idea of feeling overwhelmed and out of control, and the requirement to reclaim control of one's own life.
