Reece Pitman, 12, of Solihull, Birmingham, who first heard whistling then saw the shadowy being, was very terrified as he showed the footage to his 38-year-old mum Tonia.
"Reece looked scared witless," the Sun quoted her as saying.
"In the clip a white shadow appears from my bedroom followed by the dark image of a man.
"It crosses the landing and disappears when it reaches the banisters," she stated.
The shadowy image had appeared days after his nine-year-old sister complained that someone was mysteriously finishing her jigsaws at night.
Tonia, who works as a sales assistant, said she consulted a psychic who told her the ghost could be friendly.
"I've had a tough time recently as my husband left me. I didn't believe in ghosts - but I'm thinking of the spectre as my guardian angel," she added.
Julian Banks of the British Paranormal Society said the film was "potentially the best image of a ghost in years".&13;&13;
