Erin Potter, like many kids growing up, had an imaginary friend.
She said they had a game where he would take her doll clothes or toys and hide them, and then she and her sister would find them.
Then Potter had a thought: Imaginary friends can't move things.
It was then that the Aliso Viejo resident "realized what a ghost was."
In June 2010, Potter and friends Kirsten Thorne and Marsha Covert-Garcia started Paranormal Housewives in an effort to further their interest and education in paranormal investigations.
The women started the all-female group as a response to the male-dominated groups they encountered.
Potter would try to join other investigative groups, but she said the mostly-male groups would plan trips spontaneously, which was difficult for her with two kids and a husband.
"We were tired of the drama," Potter said with a laugh.
In their group, organizing investigations around family's schedules is the norm, with most of the wives having at least one child.
