Reflecting on Type-Moon lore, Dreamlike Charisma should be representing Charisma related to affinity with magical things, hence Merlin.

She's well-known as good learner and shown interest to things unusual to others on same boat with her by that time standard, which distinguish her from others.

Such trait turned out made several people on her era thought of her as charismatic figure. I'm not sure what skill could fill such explanations, so Dreamlike Charisma, also Pursuit of the Unknown, at low level.

Sadly I can't tell what is her occupation because it would become too easy to guess who is she as the number of woman on her occupation, with fame enough to be a Caster, are not many.
