If you're a horror movie fan, you've probably heard about Winchester, the spine-tingling new ghost movie starring Helen Mirren.
The movie's trailer teases a story about a wealthy heiress haunted by the ghosts who dwell in her incredibly creepy mansion. But the scariest part of this story is that it's true.
The Winchester Mystery House is a very real mansion in San Jose, California, and every year thousands of visitors tour the spooky building.
It was the product of Sarah Winchester's haunted imagination. Winchester's father was the wealthy founder of the famous rifle company, and her husband was also a successful gun manufacturer.
But by the 1880s they had both died. Living alone in an eight bedroom farmhouse, Winchester began adding extensions to the building.
Then, things took a strange turn that no one can explain. Winchester spent the next 40 years obsessively building, tearing down, and re-building her massive home.
The final product is totally eerie, and there's a chilling paranormal explanation behind Winchester's designs.
