In 2009 I began to experience lightning-like streaks in my vision, sometimes when I opened my eyes and turned my head to look at my alarm clock.

One morning, after I had been seeing these streaks for many months, I was jerked awake by a flash that seemed like carnivorous animal leaping out of the darkness.

I awoke sweating and with my heart pounding. I never saw the lightning streaks again. Instead I would sometimes see a series of groups of bright curves which formed a trail across my vision.
