Yo, that's such a cool dream and it's cool to talk to a Lakota. I love trippy dreams.
I had a dream last night where I was walking through a forest with some of my older relatives who had passed away (dad and grandpa) and we were just talking about life and I was asking for advice. I can't remember anything that was "said", but the dream resulted in the same sense of peace and calm that I normally got when talking to them irl.
You can always stop trying to distinguish between dreams and reality and just accept whatever you're experiencing as a sort of superposition of both.
