Can someone interpret these dreams for me?

Okay well ive had two dreams. One about 3 days ago, and the other just last night. Well considering they both have to do with ex-girlfriends, ill have to number them EX 1 (my ex from about a year ago, it was somewhat mutual but i never really got over her) and EX 2 (an ex that i just broke it off with around a week ago who is pretty crazy and EXTREMELY clingy) so ive been having alot of mixed feelings about these 2. The first dream started out with me and my cousin walking to the end of a line in this parking lot. We got about halfway down the line when i notice EX 1 coming out of the line. We had one of those moments where we both step in the same direction right and left. Then out of nowhere she hugs me and we start talking and hit it off immediately. We all 3 wait in line and when i get to the front, its like a pharmacy, but with a drive thru like window and a man in a lab coat handing out medicine. I asked the man for some prescription (which is weird cause i dont take medicine) and after i got the bag, me, EX 1, and my cousin got into my grandmas truck. My cousin was driving and me and EX 1 were in the back seat talking and flirting as we were holding hands. We were driving her home (i could recognize the street) and i saw out of the window, EX 2's brothers and some of their friends riding bikes. And they notice me and EX 1 sitting in the back seat. Immediately after i see that my phone starts going off and i know its EX 2. I dont answer and then EX 1's phone starts going off as well and i look and it is EX 2's number. EX 1 opens the phone then just closes it and she kisses me afterwards and i tell my cousin to go one more time around the block and my 1st dream ends there. My 2nd dream starts with me in some sort of convention or something. There were a bunch of booths and showings for things and everyone was in costume (which is weird cause ive never been to a convention in my life). There are tons of people i know at this convention walking around but i dont really acknowledge anyone. Im walking around when out of nowhere i notice im walking right next to EX 1. She is wearing some sort of black shirt with leather pants and heels. I asked her what she was wearing and she told me some name that i didnt recognize. I said "Oh i gotcha" and she replied angrily "No you dont!" and i started walking towards her as she was speeding up and someone called out my name and i looked in the direction to see who it was and there wasnt anyone there and i turned back around i saw her round the corner in a halfway jog and then my dream ended. I really hope someone can tell me what these dreams mean. If it helps, im 17 years old and im a Libra.
