Silver/chrome saucer. After the sighting I felt nauseas

I was inside my house when my friend called me out to come and see "this" she was pointing up towards the sky so I got up and when I looked up I seen a chrome/silver color object just "gliding" on by in the sk as if it were just observing us it was pretty foggy outside and so it disappeared for a moment I grabbed my binoculars it was kind of hard to track it down. My neighbors/friends were also aware of what we seen and they also pointed it out but I couldn't see with my naked eye, till I actually grbvd the binoculars. Anyways, once I tracked it down it was still just hovering on by and it was kind of weird because it would slighy appear and then dissappear. Finally it just disappeared. Now mind you once it was actually gone I did feel kind of sick, nauseas more like it.. ALL I KNOW IS THAT IT WAS SILVER/CHROME COLORED AND IT WAS SAUCER SHAPED.
 P. S AT THE TIME IT ALL HAPPENED THERE WERE AIRPLANES PASSING BY BUT THEY ARE ONLY OBVIOUS AND YOU CAN ACTUALLY HEAR THEM NOT THIS OBJECT!
