If there's something strange in your neighbourhood, who you gonna call?
Going on these pictures of supposedly spooky manifestations at Bradford's historic Bolling Hall, the answer might be British Gas!
That's because the strange apparitions which have somehow made it on to mum-of-two Sharon Dickinson's snaps bear an uncanny resemblance to the animated flames in the gas firm's advert.
But given Bolling Hall's creepy reputation as one of Britain's most haunted sites - tales of ghostly goings-on go back as far as the time of the English Civil War when a spirit appeared to the Earl of Newcastle and warned him against planning a massacre with the chilling words "Pity Poor Bradford" - Sharon is convinced she's captured phantoms on her camera.
Sharon, 35, a chamber maid at Cedar Court Hotel, paid a visit to the attraction with her children Lucy, 14, and five-year-old Mason.
The family make regular visits to Bolling Hall, which is within easy walking distance of their home at Parkside Estate in Bradford.
But this was a visit with a difference as, for the first time, Sharon documented the tour of the house with her digital camera.
The family enjoyed the usual thrills and spills of the museum, and Sharon experienced the usual shiver as they passed through the supposedly spirit-infested Blue Room.
But it was only when she got home and looked at the pictures that she realised the family had not been alone.
In some of the pictures mysterious balls of bluish light hung suspended in the air or collected on the floor.
And in one eerie picture Mason smiled out at the camera seemingly unaware of the ghostly globe resting next to him on the long wooden bench where he sat.
"I didn't know these were on the camera until we got home," said Sharon, who quickly checked the rest of the pictures to see if the orbs appeared in them all.
But the globes of light were only visible in certain frames, and in similar pictures taken from the same spot they were nowhere to be seen - convincing Sharon that it was not a trick of the light.
But the most chilling discovery was made when the pictures were blown up on the computer and Sharon discovered a face staring out of the apparition next to her son.
Other balls appeared to be patterned and varied in size.
"You couldn't see them when I took the photographs.
"I had to tell my son the one next to him was Casper the Friendly Ghost," she said.
Sharon said it was her first encounter with the supernatural even though she has always been a believer.
"This is the first time I went with a camera. Something is not normal. I don't like walking round Bolling Hall, it spooks me.
"I don't know what it is, but it has spooked me, especially the one at the side of my little boy," she said.
Bolling Hall was recently visited by the top ghostbusting TV programme Most Haunted, and medium Derek Acorah made contact with the spirits lurking within.
Glowing balls - or "light anomalies" - are a regular feature of the Most Haunted programme and cause great excitement with the team, including former Blue Peter presenter Yvette Fielding, when they are caught on camera.
Liz McIvor, a museum officer for social history at Bolling Hall, said it was not unusual for visitors to report the appearance of light orbs on their pictures - in particular those taken in the hall where Mason was photographed.
She said the orbs generally appeared on digital pictures rather than on film cameras.
She said: "Quite often members of the public do bring in sample pictures where they have captured blue or white balls of light in various rooms.
It's not unknown for people to take a picture of a room and then take a second one, only to find there is no anomoly in the second picture. We have never had anything on a picture that we can definitely say is a face or a person.
"A lot of people claim to have seen figures and heard noises and things like that. It doesn't surprise me that people have these experiences."
Miss McIvor said the light balls were explained by some as dust catching the light, while others were adamant it was evidence of paranormal existence.
"It could be anything," she said, adding that the rise in interest in haunted buildings had increased the numbers of visitors.
"It would be nice to find something that was indisputable proof, but I think we might be waiting a long time," she said.
To celebrate its haunted status Bolling Hall is holding free weekend performances on February 17, 18, 24 and 25.
