ok here is something to wrap you head around...

the purpose of a horcrux is to have another part of your soul enact when you get killed thus keeping you alive. Right?
so b4 voldermort tried to kill harry as a baby he had 6 horcruxes planning on making the 7th out of harry's death ? right?
well when his curse backfired he would have died.. so a horcrux would have been activated. This explans that floating mist he was in books 1 though 3
so then there would be 5 horcruxes not 6 ...nagini would make 6 not 7
i am very confused. and if that is not how it worked did voldermort have more enchantments on himself to make it so he didn't die... what were they?
