These are not apparitions by The Lady of Guadalupe, these are Close Encounters of the Third Kind. Bonafide encounters with real aliens....kinda like E.T. the Extra Testicle. These folks look for apparitions and appearances on everything from tree trunks, to reflections in stained glass and even cinnamon rolls. I read abount an appearance of the Guadalupe lady and she was reportedly wearing a Tin Foil hat and gown.
The Church investigates apparitions. Some they investigate and believe are supernatural they say are 'worthy of belief', this is the case with Our Lady of Guadalupe. Others, they dismiss entirely, and there are miriad that have been dismissed. We wait for the Church's decision on the matter. That is why we are careful when such things occur.
By the way, have you ever studied the tilma for yourself?
