This one is from Nancy McMoneagle and illustrates how cluster or serial synchronicities work:
Nancy recalls a period in her life when she kept finding pearls. Strings of pearls, a pearl bead, a bracelet of pearls. She would come upon them in the oddest places and the experience repeated itself so often, over a period of weeks, that she was forced to take a closer look. “At the time, I was working with a group of people, trying to communicate my beliefs about complex ideas. And the group just wasn’t getting it,” she said. “I finally realized the pearls represented my ‘pearls of wisdom,’ and as my mother used to say, why gives pearls to swine?” She followed the synchronistic guidance and quit the group.
