This is close to how it feels when I get a "migraine flash". 2 differences - letters you're not looking at directly (a line or 2 down the page) don't move or jump.
Often, key letters will just completely disappear. In their place is...a kind of grey blank that your mind jumps over. You could swear there's something there, and you can see it when you move your eyes quickly across the word, or out of the corner of your eye when you read the previous or next word, but it disappears when you steady your eyes on that word.
