In one case, if you watched a movie about war violence recently, or thought about the topic of war, you may dream of war at night.
Another situation needs to be aimed at the specific plot of dreaming. I believe many friends have had this dream. You fight the enemy, shoot at the enemy, and each shot hits the enemy, but the enemy can't die. In your dream, you are very nervous and anxious. Do you know why? Because this invincible enemy is often yourself, your own thoughts or distractions that you don't want to admit, or the other side of your personality. In short, it is what's in your head. They're everywhere, so you can't die. In fact, only by integrating your dream enemies, "turning enemies into friends" is the best way to solve inner contradictions. Seeing this explanation today, your dream will be very different if you don't visit next time.
