Your interpretation is also valid (if you adhere to the idea that alchemy is just a psychological discipline and flowery talk that alludes to the oniric/internal world).
It must be taken into account that each discipline has a context, a language that is its own (in addition to an internal representation system). And in the case of alchemical literature it is equivocal, multiple interpretations are allowed (mind, matter, psyche, energy).
I give a case: Fulcanelli, in his books he gives the recipe for a "particular." I know a couple of Brothers who brought it to a happy outcome.
And in fact, he has fragmented his Great Work (material operation) along the route of each cathedral. And he has shouted that Antimony is NOT the material of the Work ("his" Work).
What no one can understand is WHY his "disciple" Canseliet turned to the Dry Way of Antimony (starry martial regulus). One wonders if your Master says something clearly, why contradict him? In the case of Patrick Rivière (a disciple of E. Canseliet), he taught operative alchemy & spagyrics, and exhibited videos of him performing physical transmutations with the "Fire Stone" of Basilius Valentin (the supposed "teacher" of Fulcanelli)
Then, it is possible to apply it as a personal development system, or an operational practice. It is not exclusive: each one applies it in the internal, external or metaphysical world. I take it as the practical application of an esoteric teaching.
For example, the idea of "dew" can also be read as vulgar urine, or the Earth's "inspiration/breathing" process, from which some interesting salt can be harvested..
I wouldn't recommend drinking the unfiltered dew, nowadays (500 years after "Mutus Liber") there is a lot of pollution, bugs, etc. Although there are reports of French peasants who have prolonged their lives past 100 by drinking dew every morning, I would not dare to suffer from severe diarrhea (as a colleague told me).
In my personal case, I have collected "November dew". Not from May, because here in the southern hemisphere the seasons are inverted, so you see that the operation must be adapted to local conditions...
