I've never seen one but felt one wrap his arms around me for protection. I was riding my motorcycle home from work at dawn when a car in the oncoming traffic lane pulled out to pass. The car was so close I only had time to close my eyes and get killed. The impact didn't happen so I opened my eyes to find myself, still on the bike, out of harms way. I felt as though a warm blanket had been thrown around me and wasn't the least bit shaken up. That feeling lasted all the way home and I had the best days sleep I can ever remember having.
