What you see as real is dictated by what you believe.
What you believe is dictated by what you are taught.
What you are taught is dictated by your teachers who teach what they are told to teach even if they do not understand it.
What they are told to teach is dictated by government
Government is controlled by a civil service...
The civil service advise government according to an agenda even if they don't understand it.
The agenda is dictated from a "shadow government" that carries out the will of the rich elite
We could go further.......
Our reality can be so different if we question it, which breaks the process at the points at which those that teach and repeat information do not know why they are doing it....
