Screaming or howling

Non-lucid dream, kind of nightmare-ish full of tension/conflict, not enjoyable like most of my dreams have been lately so it stuck out. I am part of some crime fighting organization, and we and our mad scientist design a helecopter to take out the bad guys and go inflitrate their base, which is like a generic military secret concrete geometrically squarish place. We infiltrate covert ops style, black suits and all, and wind up failing, they hijack our helecopter but we escape a-ok. The dream switches to a type of video game cutscene, with six of our helecopters, now retro fitted with nuclear missle and a dozen gunmen or so, rising out of the water! <PERSON>.. Created by their version of our mad scientist. evil mad scientist. So now my ex roommate it part of their organization, R, and we are texting for some reason, like we are trying to stay friends even though we are fighting eachother. The scene switches again, and they have just bombed a tropical island, perhaps to use it as a new base. The men that planted the bomb on the island are running frantically down the mountain as lava is flowing behind them, toward the shoreline below. I am watching all this from an aerial 3rd person perspective, and see that R is on the mountain, and text him "Be safe!" and see him texting me back as he runs, the response says "No doubt here man" or something similarly macho. He is almost to the water when he slips on some rock, and the lava overtakes him and covers his left leg, leaving the rest of his body untouched. He begins to scream, howling in agony, and it is incredibly realistic and dominating my senses. It is like I am standing next to somebody who has been mortally wounded and can do nothing. Now I am in the water, swimming towards the island with lava flowing down toward my injured friend. I stop at a rock close to the shore, he is about fifteen ft away from me, and I start to splash water on to him as fast as I can, working hard, but it is doing nothing and he is still screaming horrifically. The lava is flowing down towards me and the water I am standing in is getting closer and closer to boiling. I hesistate looking back at him and then jump into the water and swim away as fast as I can. At this point my organization comes zipping into sight on a white truck on a small dirt road on the island to save me, tropical trees and sand, dark grey skies. The dream then fades. This dream really stuck out because of how intensely real the screaming was ,and it persisted for about five minutes real time. Fortunately I have not had a bad dream since this one. P.s. I am going to make a habit of posting some dreams each week, interesting, whether lucid or not just to make a habit of it and I develop my RC and LD skill sets. Hope you all do not mind.
