Our sense of self is a construct that exists in the immediate future. We feel that we are in control, like a pilot, but our part in the decision making is just on the abstract side of things. We set goals that the brain commands the body to follow. When you want to press a button on a controller to make your character dodge in a videogame, you feel like you're doing the action at that moment, but your brain has already sent the order for your muscles a few moments ago. It does that by predicting multiple scenarios from the data provided by your sensory organs, choosing one based on the previous experiences stored in your memory. That's why you get better at something the more you do it, you're providing more data for your brain to create predicitions and choose the right one. Funny enough that's how PCs are so fast these days, they call it branch prediction. So the next time you die in a videogame, you can either get good or blame your brain.
