All my life I have experienced paranormal activity and ghosts and I wonder why more people have not had the same experience. I first saw a ghost of a old lady while on a walk with my grandfather over fifty years ago and recently I have seen the ghost of my Mom who passed away on January 6th 2010. I have lived in several houses including the one I live in now that is haunted. I really wonder why some people can see ghosts and other forms of paranormal activity while other people do not. Does anyone have any ideals about this.
