Dreaming of your grandmother wanting to kill someone may symbolize your own desire to take revenge or seek justice for a perceived wrong. The person she wanted to kill, possibly the president, could represent a figure of authority or power in your waking life that you feel has wronged you or others. Your offer to help may reflect your willingness to take action and stand up for what you believe in. The park and security guards could represent a public or official setting where your actions may have consequences. The sniper rifle may symbolize your determination and precision in carrying out your plan. Killing the guards and the target may represent your desire to eliminate any obstacles or threats to your goal. The stress and fear of getting caught may reflect your inner conflict about the potential consequences of your actions. Your grandmother’s dismissive attitude may suggest a lack of concern for the potential repercussions. The police catching you and asking about the planner of the assassination may symbolize your fear of being held accountable for your actions. This dream may be a warning to carefully consider the consequences before taking matters into your own hands.
