Metchosin: I too have experienced an ocular migraine. The first time I had it, it scared me; I thought I was going blind, or having a stroke or something. I called my HMO, and during the fifteen minutes that I waited for the doctor to call me back, it went away. He told me it was harmless, nothing to worry about. However, it seems to me it could have been deadly if I had been driving on the freeway at the time! Nearly half my field of vision suddenly disappeared, replaced by a huge blank area with shimmering colors around the edges. Yeah, it's entertaining, provided you don't need to see anything while it's happening!
