Anyone can buy a dream catcher or any other item from another culture (not necessarily just tribes) from any retailer for whatever reason. Nobody should feel bad about owning one, regardless of where they purchased it from.
I will buy whatever I want, eat what I want, learn whatever language I want, and perform spiritual rituals or a rain dance if I damned well please.
