Before doing anything, your brain will visualize doing it first, even if not completely consciously. Sometimes your brain gets it wrong, or something changes/interrupts you, and will get a weird feeling or even surprised/shocked. It's basically just your brain realizing that it's perceived reality is different from actual reality, and it has to adapt to the new situation. You're assuming something is going to happen, and being confused when it doesn't occur.
