Dreaming about the end of the world is a common sign that you are feeling despair about a situation in the future. It is a sign that you are under lots of stress and feeling anxious about your own abilities and the abilities of those around you.
It doesn’t necessarily mean that something negative is going to happen, however it is a sign that you may need to take some time to relax and take stock, are your priorities in order or have things been blown out of proportion?
Dreaming that you are saving the world is a positive dream about your self confidence and ability to make a difference in the world. You are starting to believe in yourself and trust that you are going in the right direction.
This is a positive re-enforcement of your own confidence so don’t let others put you down.
