Me (13f) and another girl (my age) playing instruments in a orange band room, and then going to the stairs (very long stairwell, think hotel stairs) to get something, then we make out, and she runs away, one of my real friends in the background for some reason, and then i go to the bathroom and there is blue and red blood in the toilet, and then the next day i learn that she killed herself??
This dream may reflect your feelings of connection and intimacy with your friend, exploring your emotions and desires in a safe space (the band room). The act of making out suggests a subconscious exploration of your romantic feelings or a desire for closer connections. The long stairwell might symbolize a journey or process you're navigating in your life, possibly reflecting feelings of uncertainty about relationships.
The presence of your friend and then transitioning to the bathroom scene with blue and red blood could represent anxiety about loss or fear of harm, and the shocking revelation of her tragic fate may mirror your worries about mental health or emotional struggles in your circle. This could indicate a need to process your feelings about friendship, vulnerability, and the weight of serious issues that young people can face.
