I Had a Apocalyptic Dream?

Last night i had a scary dream and i need to know what it means. I dreamed that there was a sort of alien invasion ( their leader looked sort of like Dr. Robotnik ) and they put me in a dimension with a fake house and fake parents. When i asked my fake parents what was happening, their answer was " they are coming "( during all of this, i was attempting suicide to my hearts content because pinching myself doesn't bring me out of scary dreams ) then we were all in a saw like situation where you had to either hurt yourself or hurt others to go to heaven. By this time my best friend had shown up and we were scrambling around and helping people reach their quota. We all had little eye looking symbols floating above our heads and when it turn from orange to blue, you were going to heaven. Sara's had already turned blue and i was too busy helping people, and our symbols started to glow and we started hugging and crying and then she disappeared, and i was left in this world. Then i woke up crying. What does this mean?
