No worries! I'm more than happy to answer your questions. I don't know much about Hannibal, but I can see the similarities! There actually wasn't anything specific that inspired the story behind The Glass Coffin.
The plot was largely a spontaneous idea from around 2 years ago, though I think I was reading "The Shining" by Stephen King at the time. Overall, I thought it would be interesting to explore topics such as cabin fever and the human mind.
