This dream may symbolize unresolved feelings and power dynamics in a past relationship. Running after your ex-girlfriend who is holding a gun may represent your desire to confront her and take control of the situation. However, when she turns around and randomly shoots you, it could suggest that you feel hurt and betrayed by her actions. Looking down and shouting at her may indicate your frustration and anger towards her. Asking for a kiss and being declined could symbolize your longing for affection and closure from the relationship. Running into the reception area at school and telling them about being shot may represent your need for validation and support from others. The lack of interest and action from the receptionists could suggest feelings of being ignored or dismissed in your waking life. Being taken to the hospital may symbolize the need for healing and addressing the emotional wounds caused by the relationship. Lastly, seeing the bullet hole in your torso in the mirror may represent the lasting impact and pain of the past relationship. This dream may be a reflection of your subconscious processing and trying to come to terms with the past.
