So it's like 2 AM but I was thinking about the Dead Marshes and how there was little lights, and how they are kinda like will-o-the-wisps, and how will-o-the-wisps are actually real and are made of methane and phosphine, which are gasses formed when dead plants and bodies, and how mushroom rings sometimes grow over dead bodies. So I'm wondering if both can happen at the same time and people were just like "Cousin Jim was taken by the faeries because we saw a mushroom circle with lights around it", but actually it was just poor Cousin Jim decomposing.
