Death Dream Interpretation?

[Lolia F]

Hi, just recently I had a dream that I had a sister(no name) that was obviously in her teens(I dont know the exact age) and she had just got her drivers liscence. The thing is she was so excited to get her license that the first day she obtained it, she went driving. In my dream it was night and all of a sudden she crashed and died. I remember in my dream just seeing her laying there lifeless in the dark with sirens all over the place and people pulling me away from the scene and just flat out sobbing. I also could NOT stop sobbing which let me know that I really must have obviously loved her. After that I woke up. The thing about this dream is, in real life, I don't have a sister. I have two brothers, ages 14 and 10. I have always wanted a sister which is why I think this dream touched me so much. Also in my dream it seems like we really got along and were best friends and really close which is why I think in my dream I couldnot stop sobbing. Please help me, thank you so much
