That's a fun idea There are a few entertaining songs to use as well:

There used to be song on Youtube that went like this: We all live in a land of lucid dreams, a land of lucid dreams, a land of lucid dreams.
With the melody of Beatles - Yellow Submarine.

Then of course Nine Inch Nails - 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 Franz Ferdinand: There is no nation of you, there is no nation of me Our only nation lives in lucid dreams Lucid dreams, I'm livin’ in lucid dreams I'm livin’ on shortwave streams tonight

Haha I am going to sing all day!
