Dream about killing in war is a harbinger for abundance, prosperity, humility, longevity and gratitude. You feel that somebody is somehow disappointed in you and in the decisions you made. You are feeling withdrawn or overly judgmental. This sadly draws attention to your worries over minor problems and small matters. You are lacking some emotional connection.
Killing in war dream signals something or some place that is smelly. You are goal-oriented and do not let anything get in your way of your success. You have bad luck. The dream denotes a major loss in your life. A situation in your life will take a turn downward.
If you dreamt about killing in war:
Friction or other trouble on the job could cause you to want to quit, but worries about money might keep you from doing it. You definitely need to reassess your situation. Perhaps a change of position is just what you need now. You may have untapped talents that could make you more marketable, and you might also want to train those talents. Think about this! And if you really think you want a change, go for it.
