Consider Freud and Lacan next to Reznor....discuss amongst yourselves (note the nature of the images; the lyrics are below the video):

Right Where It Belongs

by NIN (written by Trent Reznor)

See the animal in his cage that you built
Are you sure what side you're on?
Better not look him too closely in the eye
Are you sure what side of the glass you are on?
See the safety of the life you have built
Everything where it belongs
Feel the hollowness inside of your heart
And it's all...
Right where it belongs

What if everything around you
Isn't quite as it seems?
What if all the world you think you know
Is an elaborate dream?
And if you look at your reflection
Is it all you want it to be?
What if you could look right through the cracks?
Would you find yourself...
Find yourself afraid to see?

What if all the world's inside of your head
Just creations of your own?
Your devils and your gods
All the living and the dead
And you're really all alone?
You can live in this illusion
You can choose to believe
You keep looking but you can't find the woods
While you're hiding in the trees

What if everything around you
Isn't quite as it seems?
What if all the world you used to know
Is an elaborate dream?
And if you look at your reflection
Is it all you want it to be?
What if you could look right through the cracks
Would you find yourself...
Find yourself afraid to see?
