often people think that dreams tell what is going to happen in the future - that's not true. it just means that you have been thinking about you relationship (where it is, where is it going, is it moving at all) so if you relax about this when awake, you will have a dreamless sleep
Some people believe that dreams gateways to your subconscious mind and that if you dream about something its because you have been thinking about it, even if you were just subconsciously thinking about it. But truthfully, I believe a dream is just a dream, your mind just goes in all different directions which result in some vivid dreams sometimes. My advice, It's nothing. It's just a dream, that's all. I wouldn't look too much into it.
