I have NO idea why this is happening. I've had two pregnancy related dreams within the last week.

Dream #1:

I dreamt that I had just found out I was pregnant, and the doctors told me I was 17 wks along. As to why it was 17 wks, I'm not sure.

Dream #2:

I had dreamt that my MIL came over to our house and she was bringing us meat. Like hamburger meat, steak, ect. I had asked her why she was bring all this over and she said "it's for your baby! Only two more months before you pop!" (I wasn't aware that I was pregnant in this dream until she had said something) Well, I looked down, and I have a huge 7 months pregnant belly.

Needless to say, I woke up this morning looking at my belly because it all felt so real.

Why does this happen? I am currently ttc #1. And why does the # 7 keep popping up?
