I'd say it's pregnancy hon. It's not uncommon to have strange dreams at this time. The funny things is that I suffer from these all the time - until now! My pregnancy seems to have stopped mine and I now just have eotic or really strange dreams

I know it feels awful when you wake up and it can stay with you all day, but try and remember that it is just a dream and that's it.
Hope they stop for you soon hun x x
