what does a dream about your own death mean?

So I just woke up from a very emotional dream. I had been unexpectedly hurt in an accident, and just had an hour to say goodbye before I passed away. I was fully conscious and everything I just had a crazy brain injury and they could only keep me stable for an hour (yes I know that may not be realistic). The only person that could be there was my husband, we live far away and no one else could get there in time. So I died, but death wasn't what I believe it is. I believe it's just cold darkness and that there's not an afterlife or anything. But I was a spirit I guess, and I had my body but slightly transparent like a ghost. I could go wherever I pleased so I spent a lot of time watching my husband and crying because we never got a chance to have kids, I never beat my own infertility. And I missed him terribly. But he couldn't hear me so I couldn't talk to him. And I spent a lot of time watching my dad, wishing I had spent more time with him. I was just sitting there, wailing because I was so sad and angry. And my me and my husband's favorite songs just kept playing in the background. There were other spirits too and they were making fun of me and telling me to get over it. And my husband wouldn't quit crying and visiting my grave, and I realized the songs were playing because he was playing them when he would visit. I did everything I could to hug him or talk but I couldn't do anything that he could notice. And then I woke up, my face was wet because I had been actually crying while asleep and I'm still really emotional. I know it was just a dream, but what does it mean?
