Extremely Vivid Dreams!

I am 13 weeks 3 days today. I had started having vivid dreams in the first few weeks after finding out I was pregnant. They were just weird or funny dreams. No big deal.. Now the past 2 nights, I have had the most extremely vivid dreams it literally makes me feel exhausted when I wake up because it was that intense! One night was a horrible Nightmare that felt so real that I woke up whining and crying twice. And the other night was just a really real weird dream with no purpose. lol anyone else experiencing this, on an extreme level?
