Pregnancy dreams

I’m currently 30 weeks pregnant and the past month I’ve been experiencing really bad, vivid dreams. It’s honestly so tiring as it keeps me up of a night. I get them every single night, and have countless bad dreams and it’s beginning to really affect me. I’m constantly on edge every night before bed because I’m dreading to find out what dream I’ll be having. It honestly makes me cry. I’m sure I’m not the only women experiencing them but I wondering if this is part of pregnancy or do I have a problem? 😅
