Dream About Birthday Party Ex Encounter And Flirting

I was at a birthday party with my family. The party location was sort of small, so it was difficult for all of us to walk around. My older brother was drunk, and as he passed by behind me, he sort of grinded on me!! I was so disgusted I got chills running down my back. Suddenly he grabbed me by my waist and lifted me up! He was saying it was to have fun but I was just shouting "PUT ME DOWN! LET ME GO!!" And finally, we did. A few minutes later, suddenly, while I was talking with my friend, my ex appeared! He stood next to me and tried to lean forward to meet my eyes, but I looked away. I was still blushing, though. We tried to get him to leave, but it turned out he was there to talk to my friend! Since I was living with my friend, he tried to convince HER to move to the city he was living in! She blatantly refused him, but agreed to talk more. So we all headed outside to her car. Another friend of ours came with us, and for some reason, he started flirting with me! But oddly enough, I really liked it! He made me laugh, and blush and I felt excited! Although, I glanced at my ex and he seemed uncomfortable but I ignored it... Then when we finally arrived at a quiet place to discuss things, we all got out of the car. As I was stepping out my male friend grabbed me by the waist and carried me and I started giggling and telling him to put me down! Then he sat me back down and caressed my feet! I felt so flattered and embarrassed. My ex and my female friend went to talk and me and our male friend decided it was useless for us to go along, so he said he would love to just caress my skin, so giggling, we just went somewhere else to flirt. But suddenly, he took off his shirt and said he'd appreciate being touched first. I was confused and sort of put off because it seemed so sudden and unnatural. But reluctantly, I went along with it, because he said after I caressed him, he'd caress me, next. It felt so odd to be doing such things outside...
