Dream of father, married

I'm seeing a guy who is part Asian and I recently found an old dream log that I had kept. I started the dream diary to write down all the dreams of my dad who passed away almost two years ago. The dream detailed my sister (who is happily married with a child) getting remarried to an Asian. I remember in the dream I asked my father why he was letting her remarry and he said it was OK. This dream was about a year and a half ago and I started seeing this guy a few months ago. Do you think it's related in any way?
