Worste nightmare ever. Does anyone know what it means? Please help.?

Last night, I had a dream that I died, But I don't know how I died. I just did. And I was at a softball game but no one could see me, or hear me, But only my family knew I was there, But they couldn't hear or see me either. I would write to them on paper and hand it to them to tell them somthing. ( it was the realist thing ever.) And I felt so alone and depressed because, all my friends and family went on with there life and I didn't have one to live. And then after the softball game was over in my dream, Me and my mammaw, pappaw, and sister was in the douge out and my mammaw said " The car is in your name." and I have no clue what she was talking about because, i'm to young to even drive. and then I started crying, and I looked up at the sky and it was raining and a huge Bibe fell out from the sky and got smaller to land in my hands. So I opened it up to see who's it was, And there At the time date and name of the front of the Bible said. " Demon " on it, I threw it down as fast as I could, And continued crying. And then I woke up. And I ran into the kitchen and my room to see if all of my family was okay. And got ready for my softball game. But it was so real I could feel it. But if anyone knows what this means, please tell me, I'm scared to death. Thank you. [P.s - Last wensday I got saved with my friends at church, So i'm saved, That's not the problem.]
