Jelena Vasilj and Marijana Vasilj (no relation), two school-age friends in Medjugorje, after the apparitions began, started praying together for Our Lady to also come to them. Everyday, instead of going out to play with their friends, they would use their free time to pray to Our Lady. On December 15, 1982, Jelena experienced her first interior locution from Our Lady while in biology class at school. An interior locution is different from seeing Our Lady physically as the six Medjugorje visionaries do in an apparition. Jelena said she hears and sees Our Lady with the heart, in two dimensions, interiorly, not through her physical senses. Her friend, Marijana, began receiving interior locutions three months later.
