ELI5: Why is it that your brain does such a good job of removing your nose from your field of vision normally, but once you think about your nose being there you somehow can’t not see it, that is until you forget to think about it being there again?

Your brain does this all the time! you’re breathing subconsciously right now aren’t you? Well not right now anymore because I’ve brought it to your attention, but don’t worry you’ll forget again soon. And probably while you were thinking about your breathing you forgot your nose was there.
