Harry potter 7?

i think in harry potter 7 harry has to die in order for volemmort to complete lee die because i think harry is a horcux...he has voldermort in him..he cant alk to snakes...remebre in book 4 how harry had the dream about the snake and he was the snake and how he want't to hurt dumbledore.....so in order for voldermort tobe gone for ever harry needs to die and all the other horcuxs have to be destryed.
