I've recently realized that the difference between facts I remember like some numbers and names, and things I don't remember, is that I recall them as an extremely rough image of text. Sometimes it's easy, sometimes it's hard. Sometimes I just can't. This stands out when putting in verification codes: sometimes I can hold the whole thing in my head as an image sort of like when you look at a bright object and it gets stuck in your vision where the receptors are overloaded. Sometimes I have to keep referring back every 1-3 characters.

Oddly, I can visualize things very well in specific circumstances. For example: if I spend a lot of time playing a new game, I can recall images from it and manipulate them with ease. There are times where I listen to podcasts while playing a game and images from the game pop up when I recall anything related to what was in the podcast.
