At Catholic Mass when I was a child and too small to see past those taller, a question I had, after the Priest raised the host and the wine the bells chimed. I asked my mother where the ringing was coming from.
She looked up and said it was the angels. I looked up too. What confused me further, was a week later, she lifted me up and pointed out the alter boys with the bells and the specific time to ring them.
This left me perplexed, as this did not explain the winged creature with fiery eyes that I saw and who saw me and followed me from that point forth.
