It all started when she photographed the youngster while on a ghost walk in Hessle Foreshore woods, East Riding, Yorks, back in 2013.
Hannah, who is mum to 15-month-old daughter Emma, said: "Our guide showed us this tree, and told us that some people had seen the ghost of a little orphan girl there who is looking out to sea waiting for her daddy.
"I just snapped away at the tree, I must have taken about ten photos. I was wandering around, looking through them, and then I saw it.
"I thought I had just imagined her. It wasn't on any of the other photos. Then I started freaking out. I was so shocked.
"I started crying and had to leave. I stayed over at my friend's for a few days after that because I was so scared."
Hannah's photo, taken around midnight, shows what appears to be the figure of a young girl with black eyes aged around five.
She said since then the mysterious orphan girl has appeared regularly in her dreams.
The mysterious image even left previously-sceptical partner of three years Chris Billings, 25, totally baffled.
Hannah added: "It sounds silly, but after that night I have had dreams about the girl. She's been on my mind a lot. I think of her often, and I still dream about her. I don't think she will ever leave me.
"If there was a dark room, I would always be scared that she was there in the corner, and I still feel like that at times.
"Chris is the most sceptical person, but even when he looks at the picture he can't find an explanation. There was just no explanation. I don't know what to believe anymore.
"And then I look at the picture and it's definitely a girl. I've tried to find an explanation but I can't."
The Black-Eyed Child ghost has been spotted regularly in Britain, mainly around Cannock Chase Woods in Staffordshire.
Last month a horror snap appeared to show the face of a young girl while a sinister clip emerged from the haunted woods earlier this year.
