For the first incident I had just turnd off a state freeway to go to my house in Flatwoods ky. I was coming from my then girlfriends house at the time which was in Grayson Ky. I remember feeling an overwhelimg sleepiness. I later woke up in a flat stretch of road coming into flatwoods KY. The second event happened as I was on the downwind run of a landing. Apprx 100 ft below us (my flight instructor and I ) saw a highy reflected silver red blood cell shaped.after we landed my instructor changed his toon and said it was a weather ballon. What I saw was not a weather ballon I have seen.
