Trick of the Eye?

Or the real thing?

I accidentally inhaled a bite of food whole and was gasping and trying to cough. Then I saw a flash of glowing white out of the corner of my eye, and then I was able to cough and I'm fine.

Seriously.

This all happened in like 10 seconds.

I didn't even have time to get frightened; in fact I was very calm.

I know, ten seconds is not a lot of time.

I thanked my Guardian Angel and God for sending him or her.
