Dude, weirdly enough I got success right after posting this. The way I see it is just like charging a sigil. I just gazed at the mirror, “visualized” that she was appearing to me, and sank down into trance. And just like a sigil flashing, the mirror fogged over. Eventually the fog left and she appeared.
It’s literally exactly like sigil magick. I’m screaming at how much I’ve been complicating this
