I've had dreams about the end of the world too but, only when I was living a christian life and trying to serve Christ as best I could. I mostly dream nightmares or stuff that makes no sense. Once in a great while like maybe a few times a year I may have a good dream. Even so, I prefer the dream world to this world. I know that if I want to I can take control in my dreams and do as I wish but, I had to stop that long ago because my dreams were becoming so realistic that when I was awake I began to wonder if it too was a dream and that was scary. But, yes, I too sometimes have intense dreams where I can see certain things well and feel emotion and even sensation.
