Vanishing suddenly

So I had this dream 2 maybe 3 months ago. I was with a bunch of classmates and two of my close friends. We were on a plane headed to I do not know where. We all were laughing and enjoying the flight. Things started getting a little hectic and the plane began to crash. There was wreckage everywhere and we all were okay it seemed. But we were mistaken. We all had died so it had seemed. My friends <PERSON> (H) and <PERSON> (L) were right beside me. H was flipping out and L did not seem to care too much. H looked at me and said "Oh my god Dove.. Do you see the light" Reluctantly I nodded. H-" Dove we have to go into it..." Me- "No!! H we have got the rest of our lives to live out I cannot go into it yet" L- "Make up your mind guys" *she vanished* H- "Please tell my mom I loved her and I am sorry. But I have to go and you do too, when you are ready." Me- *laughed* "H c'mon you are so not doing this!!" H-"I have too..." *she walked into the light* I looked around taking in my souroundings and noting that everyone was dead. Then I woke up. I fell asleep soon BACK IN THE DREAMWORLD I was at school. I was alive trying to laugh and be happy after learning the fact that I actually did survive the crash, but I was the only one. I went into denial about it all, but I accepted it. I told my friends that I should get back to class they laughed and agreed. I took in my sourroundings noting that everyone around was wearing black. Every time I walked past a table they would all grow silent. I walked through the crowd and as I walked by one table they were still talking. They were the only ones. I heard them say "She should of died with the rest of them." They all death glared at me. Tears rolled down my eyes and I shouted "Do not you think I think it should of been me?! I would of died in order to save all of them!!! But I could not and I have to live with it not you!!! So please just let me live miserably without your input..." I ran off. I walked on and slightly looked up in the corridor and looked into the eyes of L. I had passed on the message to H's mother and I asked if she needed me to do something as well? She was demonic and looked me dead in the eyes and said "DIE". And then I woke up. (Names changed for protection)
