Brother and sister married?

I had the strangest dream ever. I am so surprised that I even remembered this dream. My sis and I ran into my cousins at the dollar store. For some strange reason we knew that my cousins family was totally different from ours but we did not judge them. The brother and sister from my cousins family were married to eachother. The brother said hello to us and invited us to spend time together with them. We accepted the invitation without judgement of the choices they made in their life. It was a strange dream, not only were the brother and sister married, but there were some other odd things about their family that I cannot remember. I just think this is a weird dream.
