Many years ago a pal of mine was very ill she was dying and I was distraught, I could not stop crying, I cried night after night it was making me ill.  One morning I awoke with a warm peaceful feeling two arms were wrapped tight around my waist, instinctively I knew it was an angel, gradually the feeling faded, needless to say there was no one there.  This is the one occasion in my life I have no explanation for, it wasn’t scary, it was very peaceful.
