i'll try but am not sure its right or make sense.
their emotional and love connections are very strong that's why she is retrieved ! nadech feels he is losing her quickly reached out to her, pulling her back. its the mind reaching out to their loved ones to hang on, im coming kind of logic. the last nadech saw was yaya running to him he is thinking alot of her. sometimes we dream very real scenario for a message to get through.
love is a very powerful emotion. we cant explain. in reference to this ff we thought its lost but miraculously it comes back. in this case i feel is yadechs desire to be together despite their current condition, they love deeply, unconditionally and are not ready to lose their battle. maybe i dun make sense.
