It looked like a murmuration of large white birds at first, but was much too high. moving in strange patterns. was reflective. before it disappeared it had the appearance like you stand up too fast and see twinkles in your eyes. it completely vanished when the phone was raised to try and get photos of it. this was on highway 60 above the trail of tears. our family was fine health wise before the sighting but we all three became sick in hours following. when it vanished we all felt like we were in a trancelike state.
