Do you have unprompted creativity in other areas?

Like, I struggle with traditional writing, but I make miniature dioramas. It's occasionally unprompted; I recently bought frozen shrimp and thought the lid was sorta window-shaped, so now I'm making it into a window seat for a 1:12 scale treehouse library diorama. I wasn't planning the diorama first, the whole scene came to mind unbidden, and now I'm making it.

I feel like it's the same thing as what you're describing, but I don't know if you see it as different or not.
