Cover art for Wake Up lyrics by Arcade Fire

You know...I think this song is from the point of view of Alexander (from Laika). He was a cold, kind of heartless character in Laika, but here he gives his side of the story; it sounds like he's living a life that his parents don't support (ergo, maybe Tunnels is also from his point of view), and he is telling his younger siblings to wake up before they become totally suffocated, and they have power over their lives. I think it's clear toward the end that he's running away.

That's just me.
