"
And all the people say
"You can't wake up, this is not a dream
You're part of a machine, you are not a human being
With your face all made up, living on a screen
Low on self esteem, so you run on
These lyrics are basically saying that the world ("all the people") is pushing people, especially females, to adapt to what society wants them to be. "You're part of a machine, you are not a human being" - you must cooperate with society's expectations, you do not have the right to act like a real person. "Low on self esteem, so you run on gasoline" - girls these days lack confidence to be themselves so they just act the way society expects them to.
