My dream!?!

Ugh I had a weird dream until I woke up excited and surprised. I hate thinking my dreams are real till I wake up. I was sleeping peacefully until I had my dream. My dream was about my grandma taking me to some clinic. She kept saying I wanted to learn more about sex. Also saying to test me for any sexual diseases. And to make them take a pregnancy test for me. We did all of it and my pregnancy test came first. The nurse was shocked and with big eyes. The receptionist said something is up because her eyes got big. As the nurse walked our way she said "congratulations you are pregnant". I was surprised because we were pregnant and ended in a miscarriage and before that we were trying for 6 months. The receptionist started asking where I stay and all this other stuff. That is when I woke up and thought it was real. What could these dreams mean?!?!
