Probably off topic, but two years ago my dad passed away, with whom I had a special connection, I loved him very much and for a long time couldn't let go. Dad always wanted grandchildren, but didn't get to see them. Now I'm pregnant and almost every night I dream of my dad, he just is in my dreams, he doesn't say anything, he just is present. I already put a candle at church and gave candies to kids, but my dad still dreams and dreams. I'm scared because of this. Maybe someone else has something similar, what else can I do?
