There was a show on TV the other night about it, and it was pretty fascinating. Apparently, the wife (Sarah) of the late Mr. Winchester (don't recall his first name) believed that the ghosts of everyone who had been shot by a Winchester rifle was haunting her house - so in order to "escape" from the ghosts, she kept building all these rooms in the place, so she couldn't be hunted down by the ghosts. That was bizarre enough in itself.
But what was really bizarre was the fact that not only did she end up with a humungous mansion, she also had really weird additions built to the mansion - which included staircases that went nowhere or to a dead-end, doors that opened to the outside with a huge drop-off, windows that were placed in walls, and all kinds of other weird stuff. I guess she figured that the ghosts couldn't find her if they got confused by all that weird architecture.
It was a pretty fascinating story!
