A mother ended up terrified after discovering a strange face hovering behind her daughter in a playpark.
The unnerving incident, which took place in the city of San Nicolas de los Garza, Mexico, was reported by Hernandez Blankhaa - the mother of the little girl who had been playing on the slide at the time.
The clip, which was filmed after dark, shows the girl sliding down the chute to join her older sister at the bottom. At the time, nobody had noticed anything strange or unusual.
When Blankhaa went over the footage at home, however, she noticed to her horror that a peculiar face had appeared at the top of the slide just as her daughter was sliding down it.
"I did not know whether to upload this or not, but I decided to share it," she wrote on Facebook.
"This happened to my daughter four days ago. I told several people that I was shocked and asked them what's there. My daughter and her father were scared."
"I don't know why this happened or why it happened to my baby daughter... every time I watch this video it makes my skin crawl. I just wanted to share this paranormal story with you, and someone please can give me a hypothesis for this because I am in shock."
While some social media users have suggested that the figure may have been a person wearing a mask, it certainly doesn't explain what they were doing there and why nobody else noticed them.
