My very good friend's (my best female friend) dad died from cancer last October. He was creamated, The Funural is the same basicly (typicaly closed casscit). Then the body goes to get creamated and you pick the ash's up typicaly a couple days later. Its not scaryeir than any other funural, but I think its alot sadder, I dunno why but I do.
I am sorry about your grandmother
