Aw yes, super common yan sa pregnancy lalo na first trimester! One of my mum friends said her nightmares were intense around week 10-12, kaya alam ko exactly what you mean, parang ang vivid at emotional talaga ng dreams nung pregnant. It's usually hormones doing their thing, kaya don't worry too much, it will pass. Try mo na mag-relax before bed, walang heavy content, some of us nag-play ng calm music or podcast para ma-ease ang mind. Congrats sa baby!
