It's the hormones (sometimes with a dose of stress and processing of big life change thrown in). It's normal and a known phenomenon to have really weird vivid dreams. I promise you, they don't mean anything.
Il in the same boat iv had really bad dreams previously with my kids and I'm 12 weeks now and Iv started having weird dreams again, I dreamt my little boy fell out his window and I couldn't get to him in my dream and I woke up having a panic attack, I went and checked on the kids straight away! And they were absolutely fine. It really is just a dream, I try not to think about the dreams tho because there not real no matter how bad or good the dream is xx
I try and relax at least an hour before bed by doing a few relaxation techniques and calm breathing, I like to try to go to bed completely stress free, or il go and light some candles in my bathroom and have a nice warm relaxing bath and just taking it easy. I find this does help a lot I think it might have something to do with hormones and stress levels in my opinion, but just keep trying things out and see if it helps reduce those weird/bad dreams xx
I get strange dreams as well. I normally have anxiety dreams before big life events, exams etc...last night I dreamt I was giving birth and all these neurosurgeons were filing in, no-one would tell me why...so vivid and strange. I've also read it's very normal though!
