Change according to will

[Specforces]

Each individual has his or her own subjective universe in which changes can be made according to will. In each individual's subjective universe lies one's perceptions of the world, and for each individual this is a reality. Carl Jung said that “[t]he meeting of two personalities is like the contact of two chemical substances; if there is any reaction, both are transformed.” Kind of obscure? Yes. Each individual can shape another's subjective universe through many explained and unexplained processes, but is it possible for an individual's will to not only change his or her subjective universe but also the objective universe? Some might call this the "power of prayer" or something along the lines of "magic."

Does the human brain hold the capacity to change things that are outside of its own realm? If so, how would you explain this?
