Dreaming of Death

Every time I'm pregnant (before I find out) I always dream of death in my family or a family member that has already passed away. I find this VERY weird because with my first born I dreamed of death in my family and woke up crying and found out I was pregnant a few weeks later. With my last pregnancy my great grandmother (passed away 10 years ago) came to "visit" me in my dreams and told me "You're gonna be a mom again girl" and there was a little boy beside her. I woke up asap and told my Boyfriend and I said there's no way I'm pregnant, and during that month I got pregnant. Today I dreamed of death in my family AGAIN !! I NEVER DREAM OF DEATH I only did those two times. Very weird !!! Btw I did have a boy !! I have two boys
