Like I said it was circular with green lights around the hull, two red lights in the front and occasionally a big blue light would blink under it. It flew back and forth and occasionally stopping to hover in place, first over the sea which it did many times. Then it looked like it stopped in its tracks and flew in over the city, right over my house as a matter of fact. The sound of it was almost complete silence, though you could hear it ever so slightly every time it was close.. I swear, I have never seen an UFO before, and I gotta admit that I've never been this frightened before in my life. It was here for hours, almost as if patrolling or monitoring us. I know I can't have been the only one to have seen it, as it was still around at 5am, where some people at least get up to go to work.. I'm not gonna lie, I'm still pretty scared, not to mention shocked. Prior to the nights events I don't even believed in this stuff.. but now that I've seen it with my own eyes.. Well I can't stay blind to it anymore..
