It was a circular object completely black except for flashing lights.

The background of the craft was trees. Balcony is top story looking over a fielf with tall trees twenty to thirty feet back or so. Girlfriend and i were sitting on balcony when bright white light was seen hovering high in the air over the trees. We smugged it off at first as a silent airplane in sleep mode with their lights off. It wasnt until it went over the field, completely silent by the way, that we saw red and green lights show up in a circular pattern and they kept on turning on and off. My skin stood up and i was shivering at what i saw. Im still zoned out about it bad. It was completely silent. in a very abnormal way.
