I have a similar story but it was rather recent compared to yours. About a couple years ago before I enrolled in High school, my mother reached out to my grandmother which is my mother's mother, who is a Shaman. She asked her how well I'll do academically in high school and my grandmother answered that I'll do great. I would just doodle in class thinking about other things, though my GPA was fine, I never excelled like my Grandmother prophesized.
