A young girl's creepy description of her imaginary friend has left people a little concerned. It's so weird, in fact, that some are convinced she's being haunted by a ghost.

American actress, Natalie Morales shared a photo of a magazine piece, in which youngsters had been asked to describe and draw their fantasy pals.

"This is my imaginary mum Grateful," the toddler explains in the feature.

"Her yellow eyelashes mean she can see in the dark - she only comes to see me at night-time.

“It scares me sometimes but I always want her to come back. She has two babies in her belly. She’s 14 but can never have a birthday."

Yeah, it's quite something, isn't it?
