Remember that by default, your character believes everything around him. He believes there is a floor, so he walks across it. He believes there's an orc in front of him, so he attacks it. Etc.
Simply saying "I disbelieve" without any associated action doesn't do anything. (i.e. doesn't give you a saving throw to disbelieve) You have to interact with the object. And you have to interact with it like you believe it doesn't exist.
So if you disbelieve a wall, that means you try to walk through it, which, if it's real, will cause you to bump your head and maybe tweak your nose.
If you disbelieve an orc, and thus try to wave your hand through it, and the orc happens to be real, the orc clearly deserves an AoO against you for dropping your guard like that.
Another extension: if an archer is shooting arrows at you, and you try to dodge (i.e. add your Dex bonus to AC), then you are believing in those arrows. If you willingly let an arrow hit you in the chest, then are you disbelieving it. (Via interaction.)
So that's why you can't (or at least shouldn't) say "I disbelieve everything." Because then you'd bump into a bunch of walls and then get killed from not dodging any monsters.
Hopefully that makes sense.
