What the *&^% do we know?

Is what we see reality or is what the brain says we see reality? Scientist have said that when someone looks at an object the part of their brain which lights up is the same as the part of the brain that lights up when the person is told to remember the object. Most people can’t tell what they have actually seen and what they remember that eventually what they remember is what they assumed they have seen? So pretty much the brain can convince our eyes and the rest of ourselves what we see. The same goes with feelings, when you get a paper cut your brains processes the feeling. When told to remember that feeling the same thing holds, moreover sometimes the feeling we have is at a low level but once we see the pain our brain convinces us that it is more serious and therefore should feel worst. Thus making you think its worst.

I was told by a friend that you chose how you react and that you can decide how you feel. I guess in some way that is true. The mind can overpower matter. So why haven’t we been smart enough to teach our brain to overpower pain and hate and discomfort? Why do we feel these undesirable emotions? Maybe we have a found a way to drown that out, there must be a reason why drugs and other escapes are popular. There must be more to what we feel and think we feel. Learning how to choose that would be the ultimate power.
