The night guard let the ghost into the building

A strange video captured by a security camera at an Argentine hospital-hospice shows doors opening and a night guard encountering someone unseen. But the guard himself claimed that he clearly saw this woman when she entered. The eeriest thing is that when he later named the woman he let in, it turned out to be a hospice patient who had died a few hours earlier. It turns out that the guard saw either some kind of astral double of the patient, or her ghost.
