Dreams of what ur having..

Well when I was about 8wks I was having dreams I was having a boy, even in this dreams the baby name was Matthew so that is the name I picked for a boy. Now I am 15wks I go next week to find out what this little thing is, but last night I had a dream that the ultrasound was saying I am having a girl.. Which is fine with me, I already have 2 beautiful baby girls I wouldn't trade for nothing. But it would be nice to have my baby boy cause this is my last pregnancy. Anyone else have dreams like this and they be right. My gut is telling it is a boy boy, but I am prepared for a girl.
