Hi and Welcome.

This dream is about trust. Has Sav done anything recently to shake your trust in him? It may have been something little, such as talking to a former girlfriend or deciding to do something else that didn't involve you.

Have you both made a commitment to only see each other? If not, you could also be feeling insecure. I suggest you tell him about the dream to get reassurance, but don't be too forward with it. He may take it as being too possessive. Good luck.
