Pregnancy/Baby dreams before BFP? I had one before my BFP last week!

Anna
Last week in my 2WW I had a dream I was pregnant with twin girls and gave birth to them, even named them, it was extremely vivid. I've had dreams of having a baby or being pregnant but usually dreams that I have a pregnant belly and expect to give birth but then find out I'm not pregnant. 
This is our first time TTC and I was hopeful this was my month, 4 days after my dream I  got my BFP at 9DPO! 
Did anyone else experience this? Did anyone dream about having twins and then  actually go on to have them?
