I'm 32 weeks and have been getting them since the 3rd trimester, but they seem to be getting worse.
I have an incredibly loving family but last night dreamt my dad assaulted me and my mum tried covering up for him. I woke in tears and still feel very upset by it. They're so real (the dreams).
The night previously, I dreamt I was riding naked on a camel. All I remember thinking was "But I've got no bra support!" 
What is this caused by? I'm not sleeping very well at all and I'm getting a max of 3 hours a night. I'm drained.
