Look up some of the Japanese lore about Tanuki (the Japanese name for the raccoon dog). It involves magic, giant scrotums, and all sorts of delightful stuff.
If you like anime, Studio Ghibli (famous for a lot of classics including Princess Mononoke, Spirited Away, and others) did a movie called Pom Poko, which is about tanuki. If you don’t care for subtitles, the English dub is pretty good, and the voice cast stars a lot of well known (for the time) American actors.
My wife got a sleep headband with Bluetooth from some random Chinese company on Amazon. So far she’s been pretty happy with it, though she’s mostly a back sleeper. She says when she sleeps on her side, sometimes the headphone part bothers her and sometimes it doesn’t. So YMMV. If you want the exact brand I can ask her, though I expect most of the brands are selling the same thing.
