It is impossible to separate one physical event from the probable events, for these are all dimensions of one action. It is basically impossible to separate the "you" that you know from the probable you's of which you are unaware, for the same reasons. There are always inner pathways, however, leading between probable events; since all of them are manifestations of an act in its becoming, then the dimensions between these are illusions.
The physical brain alone cannot pick up these connections with any great success. The mind, which is the inner counterpart of the brain, can at times perceive the far greater dimensions of any given event through a burst of sudden intuition or comprehension that cannot be adequately described on a verbal level.
