I like living in my head because in there, everyone is kind and innocent. Once you start integrating yourself into the world, you realize that people are nasty, mean creatures. They're worse than zombies. People try to crush your soul and destroy your happiness, but zombies just want to have a little nibble of your brain.
My world had for some years been Lowood: my experience had been of its rules and systems; now I remembered that the real world was wide, and that a varied field of hopes and fears, of sensations and excitements, awaited those who had courage to go forth into its expanse, to seek real knowledge of life amidst its perils.
People become desensitized to many things going on around them. It is because they always see it on the tv, hear it on the radio, read or watch it on the internet, hear about it at work etc. Then immoral acts are tuned to a deaf ear. Then no one wants to take action or speak up for what's right. Break the cycle and have moral character.
