She is in London filming sci-fi thriller Gravity with GEORGE CLOONEY and has asked producers to investigate the converted church she is staying in because she fears it's haunted.
She's had sleepness nights due to "ghostly presences" inside the north London gaff.
A source said: "Sandra is convinced something is not right."
The paranormal patter is reportedly so bad that Bullock is suffering sleepless nights due to "ghostly presences" inside the north London church and a source claims the actress is convinced something is not right.
Bonnie Vent, a San Diego-based spiritual medium, isn't surprised Bullock is having ghostly experiences in jolly old England.
"London has a long, rich history for murder and mayhem," Vent told AOL Weird News. "The properties are hundreds of years old with many highly emotional experiences attached as well as bodies buried in the floors and walls of some properties."
Also, show business celebrities seem to have a knack for picking up ghostly vibes, she says.
"Celebrities are more open-minded, live-and-let-live types," she said. "They're already living outside of the box. Plus, they travel a lot and staying in different places makes you recognize when a room has a unique energy to it."
