My mom told me that weird dreams happen because our sleep is so light during pregnancy. She used to give me warm milk before bed, which helped me sleep peacefully.
Actually, hormonal surges, especially progesterone, cause highly vivid dreams during pregnancy. My doctor said it's a very common psychological response to major life changes.
Sometimes our deepest fears come out as vivid dreams, especially if we've had losses before. Just try to breathe deeply and remember it's just your mind processing stress.
Even with my thyroid meds keeping me tired, I had crazy dreams. Just keep taking your regular follow-ups and don't let these dreams stress your mental health.
