When Meursault is alone in prison, he finds that his imagination grows greatly, and is able to memorize every single minute detail in his prison cell. He realizes that he talks to himself, and unintentionally finds a comfort in being alone.
This depends on what your definition of reality is? I think reality can sometimes be like the Matrix- society has a powerful persuasion on what others should do or be. Hmm its only a prison if you allow it to be - Make your own REALITY and BE YOU!
I’m glad I have never given two shits about what other people think about me. I see people who slave themselves out to be accepted by people that don’t give a damn about them. I will never be held captive by insignificant people
