Dreams that come true

I had this dream when I was in 5th grade and it freaked me out. I was dating this guy and we were in the backseat talking and laughing. It was dark outside. His mom was driving me home ina black mini van. He told me a lot of stuff about him. Like where...

he works and stuff like that. He kissed me on the cheek. I kissed him back. We smiled. My smile faded away a car was coming on his side and smashed into the car. I heard him scream. I was screaming also. Then he died. I went 2 a hospital 2 see if I had severe injuries. I was invited his funeral I wore all black crying then I wokeup 2 years went by I met the guy in my dream at school. We became friends just friends. He even had the same full name. Then he got the same job as the one in my dream also how can I prevent it from happening btw I'm in highschool now but how can I prevent it if you think I should tell him what do I say please help

umm, well if your serious, dont hook up with him, and dont go anywhere wid him an his momma, and well I don't know what else to say... but that could be his tyme to go, but maybe it s not... just do the opposite from watever happened in your dream, I've had shit like that happen quite a few times in my life,
