This was actually a Star Trek dream. I was the Capitan of the Enterprise (Next Gen version).

I have a vague recollection of the plot already existing, it may be a real life episode.

We were testing a weapon system or something (the start us very foggy in my mind) and the testing 'upset' an unknown scentiant species.

Much of the detail is forgotten, but I remember the enormous mass - the creature was the size of the Enterprise. It seemed benign for it's size, but had to take is to it's masters.

Later, outside the ship, my and my crew were brought into a large, arid city. We were informed that a piece treaty had been signed between the United Federation of Planets and the Ferengi.

We were brought before the Ferengi capitan. I congratulated him on the peace treaty. Then he told me that me and my crew were still wanted. It was against the that treaty, but a personal vengeance against be and my cabin crew.

I talked with him, reminding him that both sides do things they regret or which could be evil. The wording was more emotive, but it didn't achieve results.

The Ferengi captin signaled, and human guards came forwards with phasers to arrest or kill us. Fighting broke it. I remember some of the choreography. I put my thumbs into the eyes of the person coming to take me... and the rest is the fight I'll skip describing.

The dream ended a minute later, my crew still fighting and trying to escape. We appeared to be on the winning side.
