Christians, whoever, i need help im scared!?

I think you will be fine. His dream could just mean that the wreck was him and he hurt you. if that makes sense. It could be just that even though he hurt you he didn't mean to. Go to prom and have a good time. Pray before you leave and pray when you get home. I'm a christian but if you don't believe that's fine you dont have to pray, but i will keep you in mine:)
