Crazy Dreams!?!?!

I'm having CRAZY dreams within the last month or two. That my boyfriend has shot himself, or has attacked me, or I have attacked him or other people that I am close to. What is going on?! 
My family chalks it up to my brother shot himself before I found out I was pregnant and they think it's just the stress of that and the pregnancy. I am at a loss! I don't know what to think! 
But in my dreams, the baby is ALWAYS a little girl. One dream I could her very detailed. Others it's been a blur or I don't remember I just remember pink. 
Could this mean it's a girl?! 
With my first daughter I had (less crazy) dreams, she was a girl in those and she ended up being a girl! 
Any opinions?
