The Premonition Of The Murder Of My Siblings And My Mum

I had a dream Friday and Saturday night of this weekend that my mother and my two younger siblings had been murdered. In this dream, my mother, younger brother and younger sister had been stabbed multiple times by my mom's new fiancee. It showed everything in the dream except for their actual faces. They were screaming for help and trying to plead with him to stop. It showed the blood splatter, the knife he used, even showed him washing his hands afterwords as well as getting in bed and going to sleep like it was nothing. I woke up, crying, and when I fell back asleep, I fell back into the dream and I was in Mississippi for Thanksgiving break, when my father got a call that my sibling and mom had been murdered. I woke up yet again and was sweating, yet freezing and I had the feeling in my stomach this was actually going to happen. I refused to go to sleep again that night. So Saturday night, the same dream occurred. I was at their service sitting on maroon colored stairs with 3 coffins behind me with a big bouquet of green and pink flowers. One of my very good friends was sitting with me with her head on my shoulder crying with me, and yet again after that I woke up crying. Her new fiancee is on anti-depressants and isn't suppose to drink with them but he does anyway. I'm not sure if his comment, "I'm going to end up in jail, and you're going to end up in your grave," could have sparked this dream or not. This is the most graphic, detailed dream I have ever had, and I'm not sure if it sounds more like a premonition or just a dream. What worries me is that if I have a dream more than one night it comes true 9 out of 10 times. I just want to see what other people think about this dream.
