I have a neighbor who seems to attract spirits. Whenever she comes around my house, weird things happen. There is knocking, and smells. If she isn't around my house for awhile, the ghostly happenings stop.
She told me that she has always had ghostly encounters. Her mother and many of the females in her family do also.
I had told her of a program I watched in which a pyschic explained that some people shine like white lights to spirits. They attract the ghosts simply because out of all humans, they stand out.
My friend liked that explanation.
