Gender dreams...

Brittany💚💛 • I'm 26 years old from New York. I'm currently pregnant with boy/girl twins! 💚💛Due December 2015!
I had a scan done at a private clinic at 16 weeks and she said my twins were boy/girl.  I have been having dreams the past few nights that the boy is really a girl and that it was just an umbilical cord or something. So I was just curious what your opinions are. The other baby is clearly girl.
