The same thing happened to my mom after her stroke.
There wasn't a black spot in her field of vision, it was a kind of indefinite background that didn't stand out, but didn't have any information. Her best explanation is that it was like your peripheral vision, you can "see" things to the side, but you're not getting 100% of the detail you'd get if it was in front.
But yes, she said the same thing - it freaked her out when she would move her eye slightly and something that was hidden by the blind spot popped up.
