A Marian apparition is a reported supernatural appearance of Mary, the mother of Jesus. While sometimes described as a type of vision, apparitions are generally regarded as external manifestations, whereas visions are more often understood as internal, spiritual experiences. Throughout history, both Marian apparitions and visions have been associated with religious messages, devotional practices, and pilgrimage traditions.
In the Catholic Church, for a reported appearance to be classified as a Marian apparition, the person or persons who claim to see Mary (the "seers") must claim that they see her visually located in their environment. If the person claims to hear Mary but not see her, this is known as an interior locution, not an apparition. Also excluded from the category of apparitions are dreams, visions experienced in the imagination, the claimed perception of Mary in ordinarily-explainable natural phenomena, and miracles associated with Marian artwork, such as weeping statues.
