Disc shaped object over KY skies no lights or sounds and plainly visible that it wasn't convensional aircraft.

I am only writing this because I have kept this a secret for almost 10 years now. I don't care who actually believes what I have seen but I have to let this out now. I was asleep beside a window on a second story. From where I lay I can see 3/4 of the sky and the other part was blocked by a green leafy tree like an oak. The apartment is in the city and lights from the city stop you from seeing any stars that arent bright. I woke up and looked out the window and froze. I saw what appeard to be a perfectly smooth disc. There were no lights on it like many people see only the light from the city reflecting off the bottom. I thought a baloon or an aircraft but I was shortly proven wrong. The object stayed only in my view as if I were meant to see it theres no other way for me to explain it. That fact alone scared me stiff because its altitude wasn't very high only within a few thousand feet maybe two football field lengths no more than 3. It moved from right to left in a line then up to the top of my view and then back down as if it had made an L movement. It stopped and lowered quite a bit. The disc got larger and then it rose back up, higher this time. It made a last move to the top of my view and back down then back toward the country side at the right of my view where it had started from originally. I was frozen completely through the duration and couldn't speak above a whisper. I had tried to wake my brother up but I couldn't speak. Through the whole incident there was not a single sound from the object. When it left I was unfrozen and then immediately jumped from my bed across the small room to my brothers bed and woke him up. I told him I had seen a UFO. He believed me and quickly we ran down stairs and out on the lawn to see if it would return. It never did. Wether it was extraterestrial or military I don't know. It seemed to be practicing manuvering more than traveling to a destination. Even though it has been so long, I can still draw the exact portrait of what I saw. I will never forget it as l! ong as I live yet maybe now I can rest easier. If you would like to ask me more I guess you can find me.
Date is approximate.  PD
