Our minds don't just make images and scenes in our dreams. When we read or hear stories our minds come up with imagery. So after i read a book when i look back on what i read i don't remember the words i read i remember the images my mind came up with. So when multiple people read a book they all would know and could discuss the plot but the images they produced in there heads while reading are all unique. So how much different can 1 book be to many different people? I thought this would be worth mentioning and bringing to peoples attention.
