I think aura is something most people learn to unlock at a regular school. Of course this leads to the question of why Jaune was not taught and that could simply be that his parents either couldn't send him to these "regular schools" or he just didn't pay attention in class. This has already been shown when he was sleeping during Oobleck's History Class (sorry if I spelt his name wrong). As for how the first aura was unlocked it was probably discovered by accident. But as you said dust could have been a factor in auras discovery and I actually find that idea very interesting.
