A car ride, a parachute float, and an underground school lucid dream

So I had this dream that I was in a van with about 10 other people. There was lots of noise with everyone talking and the radio going. The guy beside me said something to me but I couldn't hear it. I turned down the volume of everyone in the van and had him repeat himself. He asked me something about his right bicep and I told him my thoughts. His arm was small and insignificant. The entire car erupted in laughter even though they were not actively listening. I could sense him growing angry as we reached our destination. It was really weird because I knew he couldn't actually harm me but I felt the intent and knew that the tension was going to erupt into something at some point.

We all got out and went into a building. I went into a back room where there were a few young women just chatting at a table. There was a frosted glass window on the wall behind them and the sky was clear as the sunlight struggled to break through the opaque glass. I stood in the far corner of the room and was about to do something (don't remember; guess it wasn't important). I overheard them talking about the guy who was sitting beside me. Apparently, he was dating one of them and they mentioned that he was borderline abusive. I entered the conversation at that point because I felt like I needed to know. If it turned out to be true, I was definitely going to confront the guy. So I introduced myself. At the same time, one of his goons walked into the room and saw me talking to his girlfriend and the other women. I looked up just in time to see him leaving the door frame. I knew that the confrontation was set.

My crew and I gathered behind the building and waited for the confrontation. There was a growing commotion as the guy and his goons approached with a crowd. Before they even had time to say anything to us, I gave the signal. We pummeled them with bricks and rocks, which took a few out of the fight. And good on us because they outnumbered us 2 to 1. They still had the upper hand and they started running towards us, the leader shielded by his lackeys. We retreated to our second position just on the side of a giant tree that had fallen due to a large storm. Their numbers were dwindling down to their core members and it was looking like we could win this thing without taking losses. From the other side of the tree, our assault continued. We fell back to the last position. In our planned retreat, one of my guys stumbled backwards and was caught in a thorny vine. By the time he freed himself, they were upon him. The leader took the opportunity to show us his resolve. He picked up my friend and crushed his head. I was pissed. I took out the legs of one of his followers with 2 sharp rocks thrown at a specific angle and now their leader was pissed. He jumped over the last barricade and rushed the last of us. Most of us, satisfied with the damage dealt to his crew, had already retreated to fight another day but I was still there with 1 other guy.

Behind us was a river, rushing off into the distance towards our right. On the shore there were 2 parachutes and we were ready to go. We made a run for the parachutes, grabbed them and slung them over our shoulders and jumped into the river. The big boss stood on the shore, cursing and yelling at us as we floated off to safety. The river picked up speed and for some reason it flowed towards a giant waterfall. We slipped through the wall of cascading water and on the other side we dropped down into a smaller body of water that was unusually still. We were in a cavern. I walked onto shore and lit my torch (that wasn't soaked). The light revealed that we were at an underground school and it was covered in this dark substance. When I saw it, I was immediately hit with memories. I suddenly knew the history of this place. It was built years ago and its only inhabitant, an 87 year-old man, was waiting for the next caretaker to arrive. I was the next one. He actually lived in the school for 87 years. And then I knew the danger of what I had done. The black substance was oil and it was dripping from the cavern ceiling. I could easily have torched myself, my friend, and the building. I put out the torch. Due to the flow of water, there was no way to escape the cavern, so there I would stay for the rest of my days. Was that weird?
