A woman's tweet with an image of a creepy "demon nun" lurking outside her bedroom window has gone viral.
The US woman posted the images on Twitter, showing an eerie figure peering around the curtains.
The image turned out to be just a reflection from her television, which was showing the cover image of the 2019 movie "A Nun's Curse".
However, the woman said she got a real fright before realising the more logical explanation for what was going on.
