It did make sense, sections of specialities, like Zatanna said, to narrow focus on certain instances. It was smart. "Yeah, figuring out what spell might've caused the insanity might've led to a solution quicker." Like before everyone ripped each other to shreds -always a positive. "Right, yeah, um... it came from my... dream world though." Of course killing the caster was probably easier said that done in most cases, the benefit of her magic being stronger was just a bonus.
Areas to actually practice, where people couldn't get hurt, that would be a good thing to know, since Emma wanted to know that she didn't need to wait on Regina to learn things, but Regina was her usual go to for making sure she wasn't a danger to other people at the same time. "Um, I think we're born with it? Or we can gain it through artifacts." Since Rumplestiltskin wasn't always the Dark One, at least until he had the dagger.
"I was born with mine, I think. At least with the ability to access it." Not that she knew about that for most of Dream Emma's life. "The land in my dreams, the one I originated from, it's... like soaked in magic, but only a few people can really use it."
