What does this dream mean?

When I was little I had a couple of dreams about the world ending but not a lot. But, now that I've gotten older it seems to be getting worse. I'm 14 and having disturbingly vivid dreams is normal for me. I hardly ever forget my dreams and if I do they usually weren't that important, didn't last long, or vivid enough. The most vivid dream I remember having of the world ending when I was little was that a news cast was saying that there was "going to be m destruction happening all over the U.S. in most parts of the..." and I can't remember what they said after that. But my parents took me and put me in our truck and I remember that they brought a lot of water. I also remember the news saying that there were going to be a lot of wrecks like car crashes and stuff.My parents started driving towards downtown trying to get of of Georgia (which is where we lived at the time) and my dad was barely swerving out of the way of a bunch of collisions and cars that were completely out of control. For some reason there were bees flying everywhere and people were also crashing because they were being attacked and stung by them. As a child I had a terrifying fear of bees so that may explain why the bees were there. Before we could get to the the stop light we got into a crash and that's all I remember. My most recent dream of the world ending is very confusing and vivid. I was at a school I've never seen before and I was about 17 and had a motorcycle I was driving down a long endless road and next to it was a clean up crew type thing and they were trying to get the pollution and litter off of the side of the road where the trees were. And with each level of destruction the trees would get more and more bare and destroyed and it just scared me to death and absolutely depressed me to see nature and humanity like this. I'm not exactly sensitive when it comes to subjects like humanity and stuff like that but seeing people trying so hard to fix this just sort of tugged at my heart strings a bit. The man who was supposedly the principle of the made up school I went to told me to race to the school and warn the teachers and students and everyone there that they had to get to safety because there was unfortunately no way to fix the pollution. Also next to the trees was a marshy land that used to be a clear ocean *I'm not sure how I knew or understood this but I just did* but each day they tried to fix the pollution the water just kept getting browner and foamier and more disgustingg. So I raced to the school and one teacher and another girl already knew and were trying to get everyone evacuated. So we all went to this church down the long endless road and stayed in the highest part which was where the bells are (I can't remember what it's called but it's where the bells are that ring when it's time to go to church). Well there were about a hundred of these things and the children (mostly teens about 15 to 19) were all crammed into these things (which were actually mive and had no bells inside them) and I was with 2 other girls and one of them was a girl who had a little baby and was angry at herself and started crying because the baby wouldn't eat and she thought it wouldn't eat because she ate too much food and didn't leave enough. I offered my own but she refused. I offered again and again she refused. She then bordered a bus that somehow was on a platform type thing connected to the bell tower thing. I'm not sure what happened to the other girl, she may have bordered the school bus as well. But, then after that I woke up. Can anyone help me understand the meaning in these 2 dreams? Thnx. P.S I probably pray the most between me and my mom and dad but I'm not a very spiritual person. I'm not obsessed with God but when I do pray it's usually to thank him if I had a good day or if I just haven't prayed in a while. I like to pray for other people a lot especially my friends and a lot of times when I look up meanings to my dreams the dream has something to do with my spirituality. I don't know if this little bit of P.S. info helps but I just wanted to clear some stuff up or help a little. Please help me figure this out. Thank you for having the patience and curiosity to read this far.:).
