Deputy Editor of RAG MUSIC. JFC-certified fact-checker. I’m Sasashina, a mom currently raising an elementary schooler and a preschooler. During my student years at Kyoto College of Science and Technology, I studied a wide range of fields including sound, lighting, and video technology, building a foundation in comprehensive stage production and creative expression. After graduation, I joined a music production company, where I still work, consistently building experience in production and engaging in a variety of music-centered tasks. Currently, I mainly handle articles for children, drawing on what I’ve learned about parenting and what I feel and discover through daily interactions with my kids. I hope my work can be of help to you, even in a small way!

I’ve been playing the Electone since I was six, mainly performing Disney music, anime songs, and music from dramas and films. I post performance videos on YouTube and social media, and I also give concerts. Building on my Electone experience, I took up synthesizer and piano during my student years and performed at school-sponsored events. As a writer, I’ve covered not only music-related topics but a wide range of genres, so I hope to draw on my experience to deliver articles that make readers think, “I want to try that!” or “I want to listen to that!”

You might end up eating spiders while you sleep.

This is a bit of trivia that’s hard to prevent and suggests that unexpected things might happen while you’re asleep.

People breathe differently during sleep, and some may sleep with their mouths open.

Considering that, there’s a theory that you might unknowingly eat spiders while sleeping.

Thinking about the reflex when something enters your mouth makes the idea hard to completely dismiss and leaves an unpleasant feeling.

There’s even an urban legend that people swallow more than ten spiders in their lifetime, but it’s only about the possibility—it’s just saying you might be eating them.
