Dream About Space Crew Battling Aliens On New Earth

I unfortunately don't remember all of the details of this dream but I was part of some sort of space crew. We had a ship and the main room was a large white circular room with, I think, a circle of padded chairs in the middle. I think there was a little bit about someone with super powers but I really can't remember the details nThe room connected straight to the outside where my fellow space cadets would go in and out for the mission. Our job seemed to be going to other planets, fighting the alien inhabitants and taking over. We flew to one barren planet to battle the aliens there. I was in the ship for some of the battle, I didn't necessarily have to join so I was maybe off doing a few other things or still getting ready first. Anyway, I did leave the main room, climbed up the ladder and went through the hatch door to exit the ship. I think everyone was wearing white space uniforms, the type of typically see in Sci fi movies. The battle went on (I don't remember it too well) and we won then went off to another planet. We arrived at a place called New Earth. This was an inhabited planet that had lots of buildings, it really did look like a futuristic Earth city. Again, we won the battle and New Earth was ours. The dream then either skipped ahead of this was a second dream connected to the first. I was now in a very large black room. It was not empty, there were people and furniture. It seems it was some sort of communal area but very futuristic and minimal? There were some conveyor belts on the floor, in the far left there were showers. Everything was black. I unfortunately do not remember the details of the people but there were about 7-8 people, I just don't remember exactly what they were doing. At the back was 2 doors connecting to a small hallway with grey carpet and it connected to 2 back rooms. They looked like old-school cheap office rooms. Small with white paint and gray carpet and outdated furniture. Some people went to the back rooms and I was going to go too until one girl (unsure of her age but she seemed young like teen/20s) wanted to watch TV in peace but of course the back rooms were now being taken. I took her through a door on the right side of the large black room into a white hallway. We went up a little slope and entered a room on the left. The room had been part of the spaceship/fleet that my space crew used to roam around in. It was a cosy room that was decorated. Gnar from League of Legends was there. Me and the girl were trying to close the door but Gnar wanted to do it and wasn't doing it correctly, I told him to let us close the door and he did. Then I told her to watch out for anyone in the room. There was a tall dark shadowy figure which was likely an alien enemy? Gnar helped me quickly get rid of the figure. I explained to the girl that sometimes enemies get in (I don't know how they would) but there is only an enemy in the room about 10-15% of the time. Gnar found a little bug to play with and messed with that. I showed the girl the huge TV screen which had controls at the top of the screen. 2 others had come to join and watch TV. I asked if they wanted to see what New Earth looked like then I opened the blinds and there was the cityscape of New Earth. I wonder if they didnt know what it looked like then did they not know we were on New Earth? There were no windows in the large black room, the back rooms or the white hallway, so maybe they didn't know or hadn't seen the outside before. I wonder why. Relevant details: I watched Doctor Who last week and one of the episodes involved them being trapped on a giant spaceship with a large white main room so I think that's where the spaceship is from though mine was much smaller! Doctor Who might has also influenced the whole fighting aliens and visit g new works thing.
