Anyone having them? I'm 32 weeks +2 and last night had really restless sleep. Had a dream I went into labour early (around now) and as I was giving birth I felt really sedated and out of it. It was quite freaky but ultimately the process was actually really quick and painless - I was saying "Oh that wasn't so bad" 
So maybe it wasn't actually an anxiety dream because although I didn't like the feeling of being out of control, maybe it was my subconscious's way of telling me it'll be ok.
