Military UFO dream

I remember this started out that I was in the military. I'm not sure what branch it was but I was wearing a khaki uniform. I remember that I was trying really hard to impress a high ranking official (General, maybe) with all the research that I did that was in the room with a few other officers like me. The entire dream reminded as being around the same time as the Andy Griffith show, why that came into mind, I'm not sure but it seemed that was the time era I was in around the 1960's. After the meeting was over, we all left to go investigate something. It seems like we drove forever and came to (another) Mayberry-type town again. Everyone's style was outdated from the 60's and even 50's in some cases. There was something that was halfway buried in the ground and fragments of stuff all over the place. I came up to the side of it and touched it and it felt like cold metal. It was about 50 feet long and shaped like a submarine but had a polished metal look to it. The funny thing was that civilians and military were both there looking and guessing what it was. After questioning the civilians, we went over a lot of area making sure there were no other parts. We went one last place to find a group of people to talk to in a small bookstore at the edge of town. The outside looked deserted but once we went into the store through the back, we found there were a lot of the townspeople holding hands and singing around something big in the middle of the room. Suddenly this room looked larger than it would have been from the outside as there was a complete but wrecked UFO in the middle of the room. I didn't recognize the song or what kind of music they were singing but the whole scene creeped me out bad even in my dream like they were in a cult or something. I can remember seeing the General walking in greeting with several people which further puzzled me as to just what was going on. I remember looking at the UFO and it was like 2 plates put together with the bottom plate being bigger than the upper plate. On the upper plate where was a series of square portholes that were empty and dark and dusty like this thing had been there for a long time. I don't know what freaked me out worse, the people or the situation that I was in...

I hadn't been thinking of the military, UFO's or the Andy Griffith show lately so I'm not sure what sparked this dream. I'm not sure why the end of this dream bothered me so much but it did, it really creeped me out. The people looked weird and inanimate while they were singing or praying or whatever they were doing.
