Made me feel weird, hovered, and then became invisable

I had left a ball out side and I wanted to get it. My brother came with me, we went around the back of the house. I grabed the ball, and we headed back inside. But I got this weird feeling to look up, so I look up and saw this china dish shaped thing. I noughed my brother and told him to look up. We look at it for about 2 or so mins. It was hovering over a Football field next to my house. It did not move much, but it went from left to right a few times, like it was checking something out. But then it headed out at a slow pace, I think it was to the South. While doing so it like became invisable. After that I did not see it again. Let me say that it was about 200 or so yards up in the air it was very visable.
Date is approximate.  PD
