A beautiful mind has hallucinations

IT is good to dream big.
But be careful to separate what may be impractical from what is practical.
The dreams that we have when asleep are just that – dreams.
Some may have a practical use.
In Grade 12, I dreamt that I missed doing the exam for my favourite subject.
That “motivated” me to be careful about how I spent my days before the exams.
The dreams that we have, while asleep, are created by the brain when it brings up information stored in the subconscious mind.
The conscious part of your brain is the part you use when you are awake.
Some people, under different circumstances, may see people, things or events which others do not see – and which may not be real.
The mathematics genius John Forbes Nash Jr is one.
In 2004, I saw the movie A Beautiful Mind.  It was based on the life of Nash who received his bachelor and master’s degrees in mathematics when he was 20.
Nash’s mother was a school teacher who taught English and Latin. His father was an electrical engineer.
The parents knew the value of education and while Nash was still in high school, they arranged for him to do university mathematics. That enabled him to study advanced topics.
While studying theories in mathematics, Nash began seeing people who did not exist.
Nash believed he had a roommate who had a niece and he was hired by a supervisor from the US Department of Defence to crack codes.
In fact, Nash was suffering from schizophrenia and was imagining things. The decisions he made as a result of the illness jeopardised his and his family’s life.
He was put into a hospital and was under medication for many months.
At one point, Nash realised that the niece of his roommate never grew older. He knew these were hallucinations.
For him to come out of that state, he used simple logic and separated those things he knew were conjured only in his mind from what was real.
His life shows the need to be focused. One must not be distracted.
Nash returned to normal life and is still teaching and researching mathematics at Princeton, USA.
Nash was awarded the Nobel Memorable Prize in Economics in 1994 for his work in Game Theory, a field of studies that is important in economics, business, computing and military theory.
