I’m not a religious person, but I do believe in ghosts. Not the ghosts of the dead, but the ghosts of the living. The ghosts of people who, because of a trauma, have lost their sense of themselves. Who feel, in some fundamental and inescapable way, that they are not real.
This is a very powerful statement since it goes deep into how human emotions work. We almost become ghosts after suffering trauma. We lose a part of us that keeps us alive. We slowly rebuild and feel alive again but it's almost like walking ghosts when you lose a loved one or go through a traumatic experience.
