Mercenary dream

I was in a space ship of some sort. The crew was civilian, but they seemed to be some kind of mercenaries. We were debating what to do because apparently we’d been attacked by some kind of aliens. There was one last person that we were unsure whether she was “infected” by the aliens. There was a very harsh debate as to whether to throw her out of the airlock.
After much arguing it was decided she would have to wait outside the ship until we figured out what to do. Apparently this ship had an “observation deck” that was physically outside the ship, but had a contained air bubble you could breathe. So I was the one who got to escort her out. As I closed the airlock door that lead to the deck, she gave me this sad look.
Shortly after that we landed on a planet. Several of us got out to look for provisions. Apparently not all the crew members were mercenaries like us so we told them they would have to wait behind because it wasn’t safe. We got out armed with heavy machine guns.
Here it’s starting to fade, but I do remember walking around this large building that was surrounded by people just hanging out or partying and all of them were armed to the teeth. Part of our group left to find restrooms and I separated to find, I think, ammunition. We were still afraid the aliens were returning. I recall jumping over a large pipe and that’s about it.
