Like most parents, Bonnie Moore has a video monitor in her baby daughter's room so she can check she's safe.
But one day when she had a quick look to see if little Athea was asleep, she spotted something strange in her cot.
Athea was almost out of shot, but it looks like there is something terrifying lying just behind her.
Bonnie, who lives in Norfolk, said: "I've tried to think of any possibility but nothing adds up. The features are so clear.
"I honestly don't know what to do."
It looks like there is another child or a doll lying behind Athea, who will celebrate her first birthday next week, but according to Bonnie there's nothing there.
Bonnie added: "My daughter is at the bottom of the screen. If you zoom you can see her head and body then this *thing* laying behind her.
Other parents have been quick to agree that there is definitely something there, and many of Bonnie's friends believe it's actually the spirit of someone very special.
She lost her brother when he was just nine years old, and the figure appeared just a few days after the anniversary of his death.
One woman wrote: "Wow hun - I am connected with my spiritual side, this is definitely a spirit that I can see and it is amazing that you have managed to capture that.
"I feel it is a young boy, possibly a relative or another child of yourself, he is giving protection over your little one and will watch them often whilst them are sleeping to make sure they are okay.
"There is nothing to be afraid of, this is amazing actually. A beautiful angel and a beautiful little daughter."
One added: "Ahh that's amazing! I've always been sceptical about spirits but this makes me want to find someone who can see if I've got any spirits nearby."
Another wrote: "There is a young child cuddling Athea babe."
A friend commented: "This child's a family member. A friendly spirit watching over Athea."
