Ya I was shocked when I searched for other such accounts of disguised angels. Many people had very similar descriptions where their words and presence a very powerful, the feeling of the holy spirit on you, and they often seem to vanish inexplicably. I saw this verse, "Do not forget to show hospitality to strangers, for by so doing some people have shown hospitality to angels without knowing it." -Hebrews 13:2. And several other instances in the Bible where angels were not recognized immediately. I'm very grateful.
