Do you believe in sleep premonitions?

It did happen to me. There was a family friend. We hadnt gotten along well in like forever. I had a dream of her wake. It was all these people in her living room crying and dressed in black...just real somber. I woke up and told my mom who said just to blow off. The family friend died a day later from breast cancer. I still have dreams or predictions that come true...but not as weird as that.
