Dreams about being in a war video game can often symbolize feelings of conflict or competition in your waking life. This aspect of your dream may reflect internal struggles, challenges you're facing, or a desire to take control over certain situations. The gaming environment suggests that you might feel distanced from these conflicts, as if they're part of a simulation rather than real life.
The car crash with your girlfriend could indicate fears about your relationship or concerns regarding the direction it is heading. Car accidents in dreams often symbolize a loss of control or feeling overwhelmed by circumstances. It may be beneficial to reflect on your emotions and communication within your relationship.
Consider asking yourself if there are areas in your life where you're feeling pressured or out of control, and how that might be affecting your relationship. Open dialogue with your girlfriend might help address any underlying concerns.
