First off congratulations!!

I hope all has been well for you during your preganancy despite these horrid dreams that 'yes' we do experience. Personally I think mine were related to my anxiety levels and definately my hormones which didnt leave me being a very happy vegemite most mornings.

In some cases its just a whole bunch of our worries and thoughts put into one scenario which can be very disturbing, Ive heard that a massage and a hot bath can help a better nights sleep and just thinking happy thoughts before bed is supposed to help too.

I Hope all goes well for you.
