What does my dream mean...is it gonna happen?

I had this dream in 5th… maybe 4th grade. It was a dark night I was in a mini van with a guy he said he was my boyfriend and we got into a convesation about each other. we were so happy. we were laughing having fun but then a drunk driver came and hit us on that guys side of the van. there was blood everywhere the glass from the window was on digging in my hand. some of his blood was on my clothes and on me. I just cried and yelled. I went to the hospital to get some stitches. I went to his funeral crying. while the preacher was saying stuff like they normally do at funeals. Then I woke up still rememering what happened. 2 years later I met the guy that died in my dream at school. We became friends. now at highschool I keep on having flashbacks of the dream. Bits of peices from the dream. I could listen 2 songs and I’ll start crying because it reminds me of the dream. I don’t know what it means. Is it gonna come true. Should I tell him.
