There really isn't a good way to tell a relative stranger that you think dead people are trying to tell you something. It's personal information. It's like telling someone you just met that you have a yeast infection. It might be true, but it's not the kind of thing people want to know about you. Plus, you know that every time they see you after that it will be the first thing they think about: There she is, the girl with the yeast infection/ghost problem.
