What's happening in my respiratory system

My cilia, Rip-Van-Winkle-like, have just woken from a decades-long slumber. "What the fuck???" they are exclaiming, "Who trashed this place while we were sleeping? What the hell is going on here?" I'm sure the level of rotten I feel is just due to the cilia breaking out the Dyson and whatnot. Or maybe they're using a back hoe for something.
