Dream about a peaceful world is a message for your return to an aspect of yourself that is innocent and spiritual. You are putting up a front instead of being your true self. You may feel that someone is pushing their beliefs and ideas onto you. It is a signal for your attitudes of courage and violence/passivity. You are at ease.
A peaceful world dream is a premonition for peace, harmony and profitable business ventures. You are hiding an aspect of yourself or that you are covering up something. You need to move toward a higher level of awareness and feeling. The dream is purification and insight. Something in your past will prove to be extremely important to your future.
If you dreamt about a peaceful world:
The past seems to come back with a touch of sentiment and nostalgia, as a friend or love interest makes a reappearance. This should be quite an interesting experience, and you probably have a lot more in common now than you did in the past. What transpires after this meeting may very well be a new chapter in an ongoing drama.
