Well, yes, sometimes "irrational" things are indicative of a deeper issue, e.g. Dad told me Mom left because I was messy, and if I keep things tidy I can keep people from leaving me and I will be OK.

Perhaps she's going through a rough patch, and this "I need a tidy environment" is how she's able to express it. Maybe she feels ignored/neglected/etc, and this is how she's able to express it. And it could be that you've dictated that things must go your way in other areas of the house/relationship, and here is where she feels comfortable asking that she not need to walk on eggshells, for things to be her way for once.

One thing to remember is that each of us has "irrational" requests when seen from the outside, regardless of how logical and reasonable they seem to us. Having a heart-to-heart where you both sit down with the mindset of "us vs the problem" could determine the root, which is the first step towards finding a true solution.
