This is the spooky moment the ' ghost ' of a woman walks through the doors of a hospital in where she had died the day before.
CCTV footage shows a security guard at Finochietto Sanatorium in Buenos Aires, Argentina, greet a patient only he can see and directs her to a doctor's office.
But hours later, when he checked to see where she had gone, spooked medics told him the only patient with that name had died yesterday.
In the footage, the security guard can be seen getting up from his chair with a clipboard in hand to let someone in.
He can be seen allowing the 'patient' into the lobby before cordoning the area off again.
Bizarrely, he can even be seen chatting to the visitor and offering them a wheelchair before they apparently decide to go to the doctor's office on foot.
Local media first reported that the guard had received an elderly woman asking to see a doctor at 3.36am on 11th November.
Hours later, on noticing she had not left the doctor's office, he called medics.
But the medics replied that they had not seen any patients.
When they asked him for the patient's details, he told them her name.
But they replied that it could not possibly have been that woman, as the centre's records showed that a person with that name had died the previous day.
The spine-chilling images did the rounds on social media before local media revised its version of events.
A spokesperson for the private care centre later explained: "It is the door to one of the entrances that is open after hours, it is the entrance to see the duty doctor.
"As it was broken, it opened by itself 28 times during the 10 hours between Thursday night and Friday early morning."
Staff at the centre believe that the security guard - from an external company - attended the 'invisible patient' as a joke.
The spokesperson said: "There is no entry record of any person at that time. This gentleman pretends to be writing something, but when you go to the registry, no one appears."
However, the spokesperson added: "No one entered and no one was registered either. But everything is under investigation."
Regarding the spooky version of events previously reported, the spokesperson said: "People are born and die every day in this sanatorium, so it is very difficult to relate this episode to any death.
"But it is ruled out, first of all because we do not have the name of the person who supposedly enters, since the man seen in the image did not write anything."
