Recently i have been in this extracurricular class at school and the girl who leads it is a sophomore at school, I am a freshmen. I don't know if it's me but I feel like she flirts with me and even calls me pet names. She is in a relationship with someone but I don't know if they still are together. I have seen them fight once and I haven't seen them together ever since. She talks to me and offers encouragement. I also have some feelings for her and they are also immemse. Last night I had this very very realistic dream in which she wanted to be my girlfriend I said yes and then we got permission from our respective parents and they agreed. After that we were very happy. But I could sense this imense feeling of happiness so so very real. In my dream I was very happy that it had happened. I woke up and I still felt it was real. Then reality kicked in and I was disappointed and mad that it wasn't real. This was a VERY REAL dream I hope that someone can interpret this so i can finally figure out what it means.
I think the dream is about what you are hoping would happen. You should find out exactly what is going on with her and the person she is/was in a relationship with. It sounds like she could want to be in a relationship with you or maybe she is just flirting/leading you on or you are misinterpreting the signals she is giving you. The dream can be a way of giving you confidence so you can approach her about this.
Sorry for being blunt here but if you like her there is no use hiding it. Trust me i'm a senior at my school. Go up and talk you may find out she's looking for a strong shoulder for her to cry on. She may really like you. Who knows, what I do know is be careful High School Romances are DANGEROUSLY OVER-DRAMATIC.
