Soap bubble type orb landing

It was a beautiful sunny day. I went out and felt a need to look at the sky. I saw what seemed to be a mylar balloon. It was getting closer, as it did, it was getting smaller. I said to my husband, look at the balloon. He did and went inside. I kept watching it as I saw it was no balloon, but a transparent type or that seemed to be on a direct path. It sparkled like a bubble, almost holographic in nature. It was moving quickly and directly to me. It hovered a few seconds above my head, but I didn't try to reach up and touch it. It really reminds me of the bubble the good witch comes to Dorothy in , wizard of oz. It started out the size of a truck tire, but as it came close,but was softball to dinner plate size. It went to my neighbors hedge, where it seemed to be almost sucked into the ground. Like magnetic or as if it was docking. Our dog continues to investigate that spot. I will never forget this odd incident. I feel as though the thing had an intelligent presence. I reported it to local Mufon that week.
