Ok, the voices you hear sounds a little strange, and i think it is in your dreams and you think you actually hear them while you are awake.
And no about your dreams about the end of the world.
There is no question that dreaming of a devastating nuclear explosion, a supervolcano, or some other "end of the world" event can leave you upset for days on end. On the other hand, it is important to realize that people across time probably had similar dreams featuring the most destructive things they could think of. When you have these dreams, they are not just an opportunity to recognize the severity of certain stresses in your life, they can also give you a few things to be thankful for upon awakening to a perfectly normal world.
Overall, dreams of the end of the world are not pre-cognitive in nature. On the other hand, they can easily symbolize that some aspect of your life is making you feel like your personal role in the world will soon be over. This may be related to fears of losing your job, home, romantic partner, or even fears about developing some type of illness. You may also want to interpret this dream as an ending of a significant change in some aspect of your life. Even if the change has to do with inner landscape matters, you can, and should look forward to new beginnings. In fact, if you are trying to get rid of a bad habit, a dream about the end of the world may just be the perfect time to symbolically bury that bad habit and start over with a brand new lease on life.
When you can see the relationship between ends and beginnings, you may come to look forward to dreams featuring the end of the world. Among other things, these dreams will shake up your thought processes and give you a chance to see everything in a new light. From there, you will be in a better position to decide what things you want to keep in your life, and which things you don't want to keep. In addition, if you are afraid of something going seriously wrong with some part of your life, this may be a perfect time to confront your fears and look for ways to maneuver around the situation...
