About a year ago I had lung cancer and they removed part of my lung.after two months of complications,they decided to scrub the inside of the removal area and I kept on having complications after that surgery and was just as my state was going up and I was starting to feel better when this happened! I heard the sound like a bird hitting the window upon looking out the window I saw three orbs that were in it's kind of a circle formation they started to do this formation of going in a circle around each other and then they all took off and disappeared and that was the end of that experience.third time in my life!
