There exists a monster that feeds not on blood and meat but your mind and memory’s. A creature that is made of shadows, it is incorporeal. It cannot be harmed by any material weapon. It lurks in moments of forgetfulness and déjà vu. Each time it strikes you lose a bit of yourself. Stealing your past, who you are. Your body may live on, but the ego and super-ego are dead. Only a shell is left behind. It is another type of death.
