This dream had so many event's but it's the part of this girl I am most interested in.
My dream from start to finish

I am at a family party at my grandads old flat but for some reason he had a big garden which all the family were getting drunk at although there was some guy i've never seen before but he had the presence of family, we had a bit of an argument which ended in me having a fight with him just a good few punches then all of a sudden i'm speaking to this really beautiful girl, not fake or overdone she wasn't a step away from perfection in my eyes, she had black hair, pearly white teeth, dressed nice and fashionable while respectfully to her dignity, she asked me "do you want to drink 20 quid of alcohol with me" i replied " why are you paying put your money away my family have so much drink here" she then said "i'm only paying 8 pound" she was gazeing at me like she really liked me and i'm always confident so i was smiling back letting her know i was also interested. Immediately after she said i'm only paying 8pound a lad came into my sight from the side i've also never seen him before but feel i know him and he had a friendly nature as if he was a good friend he said "i'm paying" and then all of a sudden i'm up a tree very high and i hold on to a branch and swing, this is where things got interesting i was swinging with the branch hanging probably about 100meters high as if i was flying i could FEEL yes i could feel the strain in my arms where i was holding on to this branch for dear life i must had been flying about at about 100mph steering/controling my way around it felt AMAZING then i finally managed to land safely then 2 let's say 'dudes' run up behind me one was on a skateboard the other had a camera and i asked the one with the camera if he got what i did on tape he said "sure did bro".

I then woke up
I've dreamt about this girl so many times, i remember this dream perfectly and i could feel the physical strain on my arms while swinging. i need meaning for this dream.
I never give any love to any girl, i'm 19 with a daughter, been there done that now i live my life free i never want to get married but if i met this girl from my dream tomorrow i would marry her without question.
Why do i remember every part of this dream?
Why could i feel physically?
Why do i feel an emotional connection to a girl who is more than likely a figment of my imagination?
Could this mean something, have i seen her before subconsciously or is there a chance i might meet her one day?

Thank you for the help in advance, i hope the information about the dream has given you enough gen for you to help me decode the meaning
