As well as a mysterious 'white lady' there have also been sightings of a ghostly black dog.
Nicola McCrory, who has been holding nightly vigils at the haunted house, claims to have taken pictures showing the phantom puppy.
And with a little investigation she has uncovered a spooky legend involving the dog.
"When I contacted Warren Coates from the Northern Ireland Paranormal Research Association (NIPRA) he confirmed that the ghost of a dog had also been seen at the site a number of years ago", she said.
"The dog is linked to the ghost of the hitchhiker which has been seen at the side of the road for many years now.
"It appears to be small and black and behaves in a friendly manner.
"Perhaps the dog was a pet of the dead people associated with the road."
The Galbally woman is determined to capture evidence that the site is haunted and disprove the sceptics.
"The photographs have spooked myself and my family, but they are further evidence that something paranormal is taking place at the site."
The hollow in the Mullaghmoyle Road is fast becoming a shrine to ghost-hunters from all over the country.
However, concerns have also been expressed that the area is turning into a drinking den and a meeting-place for night-time revellers.
Worried residents have contacted the Tyrone Times warning that the ruined house is in danger of becoming over-run by vandals.
Nicola McCrory called on pranksters to stay away from the site.
"When we visited the house, the place was surrounded by people running round in white sheets", she said.
"They are only disturbing the site and risking injury."
