The Stars Look Down Lyrics

Like the fly on the wheel who says
'What a lot of dust we're raising'
Are you under the illusion
That you're part of this scheme?
Seems like a lifetime ago
You could look with pride
On your world of dreams

[ Lyrics from: http://www.lyricenter.com/e25345-rush~the_stars_look_down_lyrics.html ]
What is the meaning of this?
And the stars look down
What are you trying to do?
And the stars look down
Was it something I said
And the stars look down

Like the rat in a maze who says
'Watch me choose my own direction'
Are you under the illusion
The path is winding your way?
Are you surprised by confusion
When it leads you astray?
Have you lived a lifetime today...
Or do you feel like you just got carried away?

What is the meaning of this?
And the stars look down
What are you trying to do?
And the stars look down
Was it something I said?
And the stars look down
Something you'd like me to do?
And the stars look down
