"Old Souls" and Past Lives

Okay. Yeah. Thanks for reading this in advance.

My friend (who shall not be named until otherwise) has told me before that I have an "old soul" and I don't really know what that means. I think it means that I've been in many previous lives than others. Can someone tell me what it means?

And the other thing. Past lives. I believe I might have had a past life in an asian country. Why? Because I'm OBSESSED with culture, animals, clothing, and so forth that has originated over there. So could that be one of my past lives?

Thanks again. Rachel.
