I have ADHD (where dyslexia is a common co-morbidity). I'm not dyslexic, but I tend to experience dyslexia-like symptoms with numbers. Never letters, just numbers. It made math hell in school. Like you describe, it's not that the numbers are literally moving on the page. It's that they sort of... blob together in my consciousness, like there's a blind spot in my visual understanding, and my brain tends to fill in with numbers that look close enough. I tend to transpose numbers very very easily, swapping 6s and 9s, 2s and 5s, 7s and 1s.
There's an additional layer of challenge where numbers are involved; with words, there are spellings that are obviously not words, or words that don't make sense in a given sentence. With numbers, there's no easy way for your brain to check whether what you read is accurate, because there's no equivalent of numbers not making sense.
