Aura itself though is measurable. If a detector (as in the scrolls) can interact with aura, and aura can interact with Dust, and Dust seems to be able to be set off without aura (the sneeze, unless we do go with my old involuntary aura pulse idea), then it's physical.

And yeah, these definitions are fuzzy in fiction at the best of times.
