Think abt "WHY I AM I NOW"? then you got no anwser... So, I believe "you" will have another "self-awareness" after you died, but i dont believe there are any connections between the former "you" and the later "you". As to the new "self-awareness", it could
be of anything. "you" could become a panther, a bird, a worm, and, "you" also could become extraterrestrial creature..."you" could become any creature that have "self-awareness".
Im afraid of death, Im afraid of: 1) left who I love suffered; 2) I miss this beautiful world 3) maybe I still have many things that I wanna do, and 4) Im afraid of unluckly becoming a miserable "self" after I died.
