I think it has to do with a bleed-through, from one simultaneous lifetime of being a Charles Dickensonian personage, like Bob Cratchit, who liked to organize things under proper headings. All the Shapeshifting stories go under this category, all the Dog stories go under this category, all the Astral Stories go here & so on and so on.
I definitely think I was some sort of anal, organizing, bookkeeper or accountant in another life.
