If anything, this is probably an homage to Stephen King's "It" - "We all float down here, down with the deadlights..." But what can we say? We just love that horror stuff!

Now that you say that, I'm immediately picturing Tolkiens Dead Marshes "All Dead. All Rotten. Elves and Men and Orcses." "Don't follow the lights or little hobbits go down to light little candles of their own." It must have been the "deadlights" that made me thought of it.
Welcome to my brain ;)
