Dream About Flirting And Guilt

There was someone being firty with me in my dream that was not my boyfriend and in my dream I let it happen and I don’t understand that. Fast forward I’m out in this area where I am sitting down with somebody and there’s a girl and guy in front of me with ramen noodles in her hair and I look beside me and the person I’m with got us McDonald’s to eat but I was mad because a teacher or man of authority was talking and I went over there and basically told them to shut up and then I was walking back and I felt guilty because I saw a girl and another girl gossiping not to far from them and I told that person that was with me about it.later I was walking around on the same kind of area before and saw that the railing moved so you could jump onto the floor on one side and the other opened up into a huge drop into a body of water and someone jumped off and I was going to but I changed my mind and struggled to get back onto the platform. The next stage of my dream I was around my father, sister and her boyfriend and my sister had a lot tattoos and she was shaped differently like fatter. And in that part of the dream her boyfriend had died.
