What does it mean if i die in my dreams?

So the other night I had a dream that me and my parents got into a huge fight. I told them i was leaving and my moms boyfriend said "good i hope ur brakes go out". i got into my car and started driving. i saw a train coming and i tried to beat it. but it hit my car and everything went black. (i'm still dreaming at this time) then i am reincarnated but i still remember my life as it is now. then i like teleport back to my house as me and my mom and her boyfriend are at home acting like nothing happened. the weird part is, i didnt wake up when i died. everything just went black. what does this mean?
