Did other media give you idea about FL

Exactly as it said in the title, I wanted to ask whether you had headcannons based on other media. I for example, unable to find a confirmation in this cannon, imagine the NORMAL tea to be made out of mushrooms after reading Metro 2033 by Dimitri Gluchovsky. Were there such instances for you too?

I came across a song recently that made me really think about this game: Regina Spektor | Grand Hotel - YouTube

Just a wonderful song, but also the idea of devils just doing their thing. Hiding horns under fedoras and going places for the company rather than the souls.
