A week ago i dreamt that i had a twin and that twin of mine died in my dream. What does that mean?

I'm having a difficult time figuring out this dream. If this is actually connected to a dream i had had a months ago.(I dreamt that thers a funeral paper on my plane ticket). So it's like I died in this dream of mine but later on i realized that it's not actually me but a twin of mine.I even saw the corps inside the coppin, i don't know if she resembles me because the face was a little vague but it's like it's my twin and it's like the cause of death was because she's been stabbed by i don't know who and i saw myself talking to my mom saying its too bad that things happened bec. my twin where still too young and i hope i live longer and that why cant i feel pain and i can't even felt my soul raised out of my body and my mom answered me like it's because you're not the one who died and i told her, but it's my twin and were one. I can't understand it and it puzzles me a lot. Please help me realize the meaning of this dream.
