I was on a field with my friend walking around when I noticed a low hum. I turned around and looked behind me. There was a almost transparent disk hovering about 10-20 feet away from me. There was a large dome on top of the disk. Round the base of the disk there was small circle's around 30 centermeters in diameter. We walked around as the object followed us. We started to walk home as the object still followed us. It followed us all the way home when we got home I felt sick
