If the fortune teller (at the fair) says "I see you and (blank) in a dimly lit room. You seem serious, but not unhappy" What does she mean by that? For me, the name was Sam and I already married him, so what would that mean?
The wiki notes the clairvoyant's booth in the Festival will say things based on your social status.
This information is based on the Social Status you have with the villagers. She will tell you something about whichever two villagers are at the top of your Social menu.
It does not seem to have a lot of meaning specifically, and is more for fun.
