Sofia,
It sounds like you experienced quite an intense scenario in your dream, and it's natural to feel upset after such a vivid nightmare. Your protective instincts came to the forefront as you tried to defend your friend. This could symbolize your inner strength and loyalty in your waking life. The presence of your friend suggests that your relationships are very important to you, and you may feel a strong sense of responsibility for the well-being of those you care about.
The violence you witnessed, with the girl getting hurt, may indicate feelings of powerlessness or anxiety about situations in your life where you perceive there is harm or conflict. It's also possible that the broken ribs and the bleeding signify a deep-seated fear of loss or a reflection of emotional wounds you or someone close to you might be experiencing. The attempt to comfort your friend as she was in pain could be a manifestation of your nurturing side or a desire to heal and make things right.
In your dream, the setting of a school bus, a place of transition between home and school, might represent a journey or a period of growth you're currently going through. It could also relate to the social dynamics you navigate daily, especially if school is a significant part of your life right now. The act of fighting off aggressors to protect someone could mirror a real-life situation where you feel the need to stand up for yourself or for others.
Despite the negative emotions and frightening aspects of the dream, your actions within it show courage and a willingness to face challenges head-on. It highlights your ability to take action in difficult situations. Remember, while dreams can stir up emotions and sometimes reflect our worries, they also allow us to process experiences and can remind us of the values and strengths we hold dear.
Take some time today to engage in activities that make you feel safe and loved, and perhaps spend time with friends or engage in a hobby that brings you joy. It's important after having such a vivid dream to ground yourself in positive experiences.
