8 weeks pregnant and dreams?

This is the second time I've had a dream like this, but more so. The first dream my baby was in my arms, I could see some facial features and it was a boy. Last night I had a dream where I had given birth to a boy and I had fallen In love. The dream felt so so real. I then went on to take him out to places, and do what any other mum would.

Why do I keep having these dreams and why is it always a boy? Has anyone else had dreams like this before? I'm only 8 weeks.
