[ WP ] In the near future , a man finds out that during a surgery , his brain has been altered by scientists so that they can mimic and send any sensory inputs to his brain . Pretty much anything he sees , hears , smells and touches could be a fake signal to the brain sent by the scientists

Part 1 
 
 `` Welcome to Zert Tech, are you scheduled to meet with one of our counselors?'' The friendly secretary waited for his attention. `` Oh, umm, I'm sorry I'm actually here for one of the experiments.'' `` No worries! Let's get you checked in. What is your patient number?'' The young man reach down into his pockets, and pulled out a crumpled piece of paper. He carefully uncrumpled it, and read the number out loud. `` 1... 048... 602.'' The secretary typed the numbers into her computer. She took a second glance at the computer screen, and stood up from her chair. Her voice changed and was non-inviting, `` You'll need to follow me.'' 
 
 The young man walked through hallways as he was passed along from secretary to nurse, and from nurse to doctor. The doctor inspected the young man, and interrogated him about his mental health. He preformed various thought experiments. Without knowing whether he was passing or failing each one, the young man started to become nervous. He needed this money to keep up his career. 
 
 The young man's name was Karl. Karl Welm was an aspiring poet, who was disowned by his family for not pursuing computer engineering. Now he stands here in some type of disturbing fate, facing the future he tried to part ways with. Unbeknownst to him, he had signed up to become the first human trial of a controversial experimental to cure alzheimers. Behind a dark mirror, stood scientists and doctors watching Karl go through series of tests. `` He's doing quite well. I think we have a candidate.'' Said one of the doctors. In the back of the room one scientist whispered to the other, `` What we're doing here is n't right.'' The other replied, `` So what, he is only one person. This cure might affect millions.'' 
 
 Karl was transported to another room where 3 scientist introduced themselves. `` Nice to meet you Karl, my name is Manuel. This is Sarah, and Tracy. We're going to be observing your brain today in order to understand a little bit more about how it works.'' Tracy cut him off, `` There's no need to worry.'' She put her hand on a table with a surgical drill and other menacing medical devices. `` We'll be putting you to sleep before we attach our machine to your brain.'' 
 
 Karl was trembling, and speechless he looked around to see the room surrounded by the same dark glass. He now understood he was being watch by someone or something. They were behind that glass, and if he were to die there would be no one to help. The scientists noticed he was panicking. `` It's okay, you'll be fine. Simply put, we're going to monitor and copy everything your brain and put in that computer over there.'' The scientist pointed to a large machine in the corner of the room. `` By the time you'll wake up, we will be done with the procedure and you can go on with the rest of your night. The doctors will prescribe pain medication for any discomfort after the surgery.'' A door opened and two doctors came out and prepared Karl to be put asleep. They pierced his arm with a sharp needle. Within seconds Karl began to fall asleep. 
 
 Karl awoke quite surprised that he was alive. After being cleaned up and prescribed medicine by the doctors, he left the building. He said goodbye to the secretary as he walked out the main lobby. She just stared at him without saying goodbye. Karl left that building to later that night have dinner with his girlfriend. He proposed to her that night and she accepted. The left the restaurant to their apartment where they fell asleep. Together they slept in and watched movies together like they did every other sunday. 
 
 Back at Zert, scientist stood around a computer watching and interpreting strings of code flooding the screen. One scientist said, `` This is unbelievable.'' They were watching Karl live his life after the experiment or so the scientist thought. A bearded scientist with grey hairs and crows feet walked up to the computer, `` What you are seeing is n't the Karl that left to go live his life, but a different Karl.'' The scientist were able to decrypt the code and started a live feed to show what Karl was experiencing. The restarted the computer thus beginning the experiment of the century. 
 
 Karl awoke from the surgery to find that everything was dark. Was he blind? What happened? `` What did you do!'' The words found their way to a black screen. The scientist looked at each other as if silently voting whether to respond. Karl's mind was racing. The fear overwhelmed his mind, convinced that he was blind he attempted to get out of the bed. He tried to moving his arm but it would n't move. He tried and tried but was unable to move. He screamed and realized that he could n't hear. He knew what he was trying to say but the sound itself did n't exist. 
 
 
 After what seemed like years of isolation and insanity a voice responded his prayers. `` Karl, are you with us?'' Before he could formally reply they interrupted his thought. `` Good. I know that what you are experiencing may seem disturbing but know that you are in a safe place. Karl, in order to study your mind we had to duplicate it and now simulate it from a computer. There is a Karl out there who is living out his life in ignorance of what is happening here, and who believes that he was never harmed nor altered in any way. As for you, your fate is not as fortunate.''
