Dream Invasion

I had a crazy dream last night...I was working at some sort of grocery store that looks similar to Busch's Valueland in Saline. I was working with Nate Cummings (a friend from Hish School) and a bunch of other people. Then all of a sudden we were all being led out of the store against our will and we ended up at this huge lake with a dock and there was this huge flying ship hovering over the dock and people were being lined up on the dock and the beamed up into the ship in groups. My friend Nate and me got beamed up together, but when we got into the ship, the people in charge of the ship told me there wasn't enough room for me and they were escorting me back out. I looked at Nate and felt so bad that he was taken. They were putting everyone in their own cells with bars on them. Then the next day at work, Nate was there again, but he seemed really uneasy and told me that they were taking him back on the ship again at night but it was a secret. Somebody asked him if he wanted to hang out that evening, and he looked at me really scared-like, because he didn't want anyone to know. That's about it... It really creeped me out. It was very scary and it kind of reminded me of the show Invasion. The peple on the plane seemed different than regular humans even though they looked the same.
