The Enigma of Villarrica, Chile: Ghost, Illusion, Being of Light?

Something strange was captured by a security camera in Villarrica, in the south of Chile…
Everything is calm… until a figure appears out of nowhere. But the most disturbing thing… is what happens next.
This enigmatic being seems to pass through a gate as if matter did not exist… then, it walks with total normality, without hurry… as if it knew it was being watched. But before we can understand what it is… it disappears.
What are we witnessing?
A real ghost…?
A camera error…?
A well-crafted montage…?
Or perhaps… a being of light manifesting in this world?
Whatever it is… it leaves more questions than answers.
What do you think?
