15 weeks and having crazy dreams!

Chava

So I am 15 weeks today and all the sudden I started having the craziest most random dream. And it's not about being pregnant or the baby... today I laid down to take a nap and had a dream that I was in the obstacle coarse type thing but had this scary huge, gross looking man chasing after me. It was random and scary. Why can't I have a nice pleasant dream. Why does it always have to be nightmares!!
