I returned home Saturday June 6 at about 12:15 am. Got out of my car in driveway and saw something out of corner of my eye. Did double take and saw object hovering about 10 ft. off ground about 10-20 feet away from me. Took off my glasses to see if it was a reflection. Also checked to see if it was floaters ( threads or spots in field of vision). It was neither. The object appeared as a fine line/thread about 5-10 feet across. On each end of the thread was an very narrow oblong area about 1/5 or 1/6 the width of the thread, each of which was white. The object hovered, moving up and down and side to side but remaining horizontal. There was no sound. The object appeared to be "ghostly" or transparent. I did not feel any particular way, no fear. Just amazed to see this thing! Did not have phone/camera on me, and didn't even think to run inside house to get it. Watched for about 20 minutes then went inside. Looked out window of door and still saw object. Went to bed.
