To dream of a fighter jet represents a plan or project for defensive action that is "getting off the ground." An effort or campaign to stop someone that is interfering with your freedom or independence. Feeling a threat to your free thinking. Conflict with plans or ideas. Defending yourself from competing agendas.
Negatively, dreaming of fighter jets may reflect a clash of egos. Conflict over who gets to have more freedom or control over a situation. Attempting to suppress people with alternative agendas.
Example: A man dreamed of seeing a fighter jet preparing to bomb someone. In waking life his Internet affiliate advertising account was hacked and he was trying to prove his identity to the advertiser to get his hacked account restored. The fighter jet reflected his efforts to stop the hackers theft by speaking to the company and trying to present evidence of his identity to get this money and business funds back.
Example 2: A woman dreamed of seeing fighter jets fighting and colliding in the air. In waking life she was experiencing a number of people at work fighting for control over the future of an important work project which that failed to secure. The fighter jets colliding reflected her feelings about her co-workers conflict of egos causing them to fail at work.
