What's the scariest or saddest dream you've ever had?

The scariest dream I've had is the reason I'm awake. I had died, and all I could think about was my family. In the world of the dead, I met a man from a long time ago. To be honest, I don't know why the man asked me if the moon turned blue, it was just part of a group I was in.
But I talked to my mom, telling her I was dead. She was silent. I thought about my brother and sister and woke up and cried. It was so scary. Just the thought of death is enough to make me cry.
