In the same boat, but our water's just different

I am the shipwreck with its scattered and soaked wood littering the ocean like a nest of roaches
The water smothers me patiently, and it waits to feel my body on the ocean floor
I am the captain
I stand on my ship, never leaving its side, for tonight I sleep in a shark’s stomach
The tears and rain both hit my face, as I lay on the deck and wait to drown
I am the thunder, and I am the storm
Hear me roar as I deafen all
I conduct my orchestra as loud as possible and conclude with a violent smash
I am washing the splinters from within my heart, and I scream as it pumps
Let my lungs fill with water as the broken bathtub leaks
