Nasty nightmares

Sarah
So last night I had a nightmare that I gave birth to my baby now (I'm currently 6 weeks). I was in a pub with friends and s/he didn't survive. No-one wanted to help & I had to find my own way home whilst covered in blood. I woke up crying in the night & couldn't get back to sleep & now I've been super emotional all day as well as being extremely tired! Are these dreams normal in pregnancy?? 🙁
