Craft moving and slightly wiggling left to right traveling in one direction

Ball of light that moved from northeast to southwest. No sound. Very high in atmosphere possibly above or around 40,000ft. The ball of light possibly a disc disc shaped. However too far it verify size. Traveled slightly faster than any commercial or private air craft. The UFO traveled in a wiggling almost swerving motion from the northeastern sky to the southwestern skyline at a 90 degree angle nearly directly overhead. Hard for most people to notice without Looking directly up. It had a wiggling motion almost from side to side as it continued its linear path. It did not stop, However it seemed to speed up and slow down constantly while it moved. The wiggling or slight side to side jerking motion is what stood out about the object. Making it clearly stand out. I have seen several of these from the comfort of my backyard on several occasions and rarely report them. I have seen some balls of light performing the same exact wiggle. And even respond with swelling light in intensity when talking out loud to them. I know it sounds crazy. But it’s completely true. There is much out there we still have limited knowledge of. And all things are possible, especially the impossible. Thank you for your time. I gladly give any professionals permission to visit my home and record these UFO’s whenever they would like. As the frequency of this phenomenon occurs. I wouldn’t be surprised if evidence and footage could be captured with the proper camera equipment and technology. Thanks again for your time and reading my UFO report. Take care and be well.
