All this reminds me of the very first time I saw the Japanese film, Spirited Away as a little kid! The curiosity of what are all those other spirits who also need to bathe themselves? But also not wanting to actually be seen by them, let alone find myself face to face with those yokai!
Very popular film, and judging by your love of this subject, I'm sure you've seen it or heard of it! (They are all good films though)
