The craft came out of nowhere. It was big. 2 rows of green and red bright lights (looked like Christmas Tree Lights) on the bottom and the bottom was straighter; rest of craft was disk shaped with a small top arc like top. I immediately put my cigarette out and went into the house and locked the sliding glass door. Did not sleep rest of night and am still up now. I feel tired, a little nauseous and extremely anxious.
