I believe the theory up to the negative emotions point. It wouldn't be too surprising that Negative emotions can gather and condensate (especially in a world of magic/dust), thus giving birth to Grimm. It could also explain Salem's plot throughout the entire story- she doesn't want to "destroy" humanity, she wants to make it a world without hope and only despair. Take that into condieration, and it's possible her penultimate goal is to create a font of neverending Grimm, filling the world with nothing left but endless darkness.
