Dream of church, person, woke up

My dream was weird and so unconnected. The first thing I recall in my dream was that I was walking through the streets, I wasn't alone though. There were other people. As I continued walking, the place started to look a lot familiar to me. It's the street near my university. I started talking to some people, and quite weirdly, I found myself back at the university. Then the scenery changed. I was now back at my high school and answering a test I didn't even know was about. The strange thing about this was the people who were answering the test with me. They were my college blockmates and they were hurriedly answering the test. The next thing I knew, they were all done and hurriedly passed it. I looked at my test paper and realized I wasn't even nearly done answering the test! Then the scene changed once again. I wasn't in the classroom anymore, I was out at the volleyball court in school and my teacher in high school was there. She was collecting the test papers. Moments after, a few of my high school batchmates rushed to me and gave me their papers. I passed them, including my own unfinished paper and then the dream changed again. But I realized in the end that there were papers that I didn't pass. The next part of my dream was an entirely weird scenery. I felt as if I were in this sort of ancient monastery or church. But, I wasn't me though, I was a guy. And I recall I hurriedly dashed for the steps, brushing off my other companions. The steps slowly formed into a spiral staircase made purely of stone. As I ran up the swirlng slight of stairs, I found myself in a gathering. I remember seeing all sorts of people in their habit and knights covered with steal armor. Then a fight began, and I didn't understand why. But people were being pushed to fall from the area that I just came from. I looked to the bottom of the steps, and it creeped me out how they looked endless. Each time a person was thrown out to fall, they seem to splash through and vanish. The next part is where my dream ended and I was already out of that creepy monastery-like place. It appeared to me as if I were in this kind of party and people were all dressed with odd costumes, some even opting to cosplay. The next thing I knew was that people were starting to leave and I was with this guy and I was, for some reason, aroused. So we sort of 'tried' to do it, but he refused to go any further and left me. I was still there on the ground and people were just walking by, not minding me at all like it was perfectly normal. Then came this really beautiful girl who hadn't much to wear. Quite suddenly, she started performing oral sex to me and the next thing I knew was that I climaxed. And that's where I woke up.
