Pregnancy dreams. Confused.

I have had a lot of dreams that I was having a girl when I was in the begining of my pregnancy. Im 28 weeks and im having a boy well at least three technicians said I was and today I took a nap and had a dream that my dad who is in heaven now had a big room and in his room were two other rooms and one of them had all theseblittle newborn and girl clothes. Im so confused and scared when I deliver that its a girl after all. Thats what I really wanted but now im happy and excited about my boy. I mean I would still be happy no matter what but we have but a lot of baby boy stuff.

Had anyone one been told they were having a girl/boy and ended up being surprised by the opposite?
