Are they real? Angelic presences, in cell photos, on security cameras? Or effects of light?
Always, of course, the chance of fraud. In fact, in the last video here, at least two of the sequences seem staged; in another, perhaps too much detail. In other cases, clouds are just that: clouds.
But all of them?
The videos in a moment. First, a still photo. They say — or at least one secular site does — that this can’t be real because Mary too closely resembles a statue (taken of a dying man):
There are such things as reflections, and this looks like a statue out of view may be reflecting on a glass partition, if partition there was — though the fellow dramatically improved immediately after the photo was shot, according to the site. (“The photo was taken with a mobile phone by the grandson thinking that this was the last he might see of him. Then there is news of the man’s miraculous recovery. It was a week later until the photo was retrieved and shared.”)
Anyway, a few videos. You view.
And also: you discern.
