Oh I did somewhere here, back in 1997 I was with 3 other women on the NJ border of Pennsylvania, flat farm country. It was 9:10 pm, dark out, clear starry night, and we were having a cigarette outside of a barn. I never would have noticed anything because I am not a sky watcher, but one of the women was very religious and had a habit of stargazing as she was praying. Her exclamations of 'What the heck is that??' made us all look up, there was a huge round object hovering above us, I guessed it to be 30 - 40 feet in diameter, rotating clockwise, with round flashing lights underneath it, in three colors one of which was yellow. No noise, no smoke. This thing took off to the middle of the sky, still rotating and hovering. Then it started to 'jump' across the sky, back and forth, and we started talking about what it could be, when one of the women shrieked, 'It's on top of us again!', whereby someone else said it was going to land, and we all ran for the house. I was the only one who looked back, and it took off so quickly that it only left a light trail behind it. I certainly would not want to see what was operating this thing, all I kept thinking was that it was like watching a science fiction movie. These things aren't running on gasoline or anything like that, they must be using some type of anti-gravity devices or something along those lines from what I saw.
I never tell anyone about it because you're either viewed as 'odd' or imagining things, or having vision problems, but we all compared notes and saw the same thing.
The thing that I feel is odd is believing we could be all alone in this vast universe.
I'm no scientist, but could these things be moving through dimensions?
