I was at an intersection on South Main near Bothelo in Walnut Creek. I saw what appeared to be a plane at first. It was far away and had blinking red and green lights. Then it seemed to have shape shifted into a big circle with a hollow center. There were lights around the circle and they were flashing in a clockwise direction. I can't remember what colors but there were many colors. The thing Descended and got closer. It bounced around, hovered, zigged then zagged. It told me it was okay not to be affraid. It told me that energetically. It went from far away appearing to be the size of an airplane to close up appearing to be the size of a basketball. It was very strange. I had to turn left at the intersection so I lost sight of the object but I felt calm and safe.
