Lyric discussion by iteration2 

I think it's about an escape from self-imposed conformity. We spend so much of our lives denying our true natures and desires in an attempt to fit our designated roles in society. But deep down, we all want to not only be something different, but many different things at different times.

Perhaps Mercer equates this yearning to be "a thousand different versions" of ourselves with dreams. Our dreams, be they fabulous or terrifying, give us small tastes of a life free of barriers and the impositions others put on us. And much as literal insomnia keeps us rooted in stark reality, a metaphorical insomnia might have the same effect of preventing us from just shattering our fragile yet rigid frames, and letting our true selves flow out.

But sometimes, the need to indulge our basic animal instincts and urges, be they creative, intellectual, sexual, or spiritual, force us to break free, and tell all those who would have us kept in our gray prisons of quiet conformity to go f#$% themselves.
