An ultrasound picture of an unborn baby has gone viral after a strange looking figure next to the foetus was spotted by thousands of social media users.
The eerie image was posted on imgur under the heading "A friend's ultrasound. When you see it...".
At first, the scan looks like a fairly innocuous picture of an unborn child resting sweetly in their mother's womb.
But if you look to the right of the picture, you might see something altogether more disturbing.
A grainy outline of what looks to be a woman has been spotted by many people who have looked at the picture.
Opinion is divided as to what the figure looks like, with the most popular choices being a Hindu Goddess, a mermaid or a demon.
One commentator said: "Does no one else see the demon on the right?"
But another responded: "Hindu goddess on the right side of the image."
To sum up the disagreement, subtlemrs simply wrote: "I'm seeing a friendly mermaid. Everyone else is seeing a demon. We're all weird."
The picture has been viewed more than 500,000 times since being uploaded yesterday.
This creepy occurrence isn't the first time strange things have been spotted on ultrasounds.
Last year we reported how a woman was shocked to see what she believed was her dead Granddad kissing her unborn baby in a 4D scan.
Unlike previous images, the couple said they could not recognise the ghostly face in the print out but couldn't deny that it was "as clear as day."
And its not just human apparitions that make appearances on ultrasound scans.

In July, 29-year-old Leanne Sullivan was shocked to discover what appeared to be a dinosaur photo-bombing her unborn baby girl.
The image was particularly startling as it coincided with the release of hotly anticipated dinosaur sequel, Jurassic World.
