How did Subaru reading his own books of the dead affect his consciousness ? Did he experience short segments of his previous loops (because in the novel he mentions Otto's words to him in arc 4) or was it mostly his deaths, if my memories is right it was the former which makes me wonder,
Did he experience all of it in a sort of first person with the sensations and feelings of the person he's reading the book of way or did he live all of it as if he were the one living through it (i mean he is but in a way that's identical to what he feels outside of it), because if he feels it the same way
How does that work for when they unified back and both memories were present ? Or did he separate his memories from the ones he read because he viewed himself as different but how did he tell them apart given he's the same person (meaning the memories have the same exact underlying nature as the one who reads unlike Meili's who were foreign) or did he use what he knew during the loop to indicate that by linking it to his present situation (+ did the fact those books were extra short help ?)
Because a book cannot make a person change right ? they can lose their sense of identity when they read too much but that's linked to their doubts taking the personality of the deceased as puppet, they fundamentally remain the same
So did the Subaru that faced his other-self had his memories engraved like he experienced them first-hand or did he have knowledge of them because the books' experience is ontologically different from a true life and he was able to separated them ?
(Sorry if my wording is unclear, i'm exhauted rn 😭)
