I've had a bit of a similar experience in reference to the mundane. As a kid, I absolutely hated doing the dishes or laundry (as most kids do). However, around when I turned 19 I started listening to music (sometimes a podcast) while doing the dishes and everything changed. I realized I can basically mentally automate the process of doing dishes, and almost completely shut my brain off. I'm a habitual over-thinker and usually quite anxious, so this was absolutely amazing for me. Its gotten to the point now where I almost get excited to do the dishes.

I personally don't consider what I was doing meditation, but I wouldn't be surprised if I accidentally mimic'd some meditation-like behaviors to aid in this.
