I am petrified of dying, so I try not to think about it too much anymore. Of course, during my "darker" times I did and this is what I figured out (plus one revision):

If any of my organs are good, I'd like them donated.
I want a wooden casket.
I want the flowers to be medium pink and white roses.
I want my favorite hymns played at the funeral ceremony.
I want people to cry like crazy.
I want to be placed in a private mausoleum big enough for my casket and my husband's (you know, one of those little above ground mini-"house" looking things that they used to have all the time).

And within the last two years, I've decided I want Samantha's ashes to be placed in my casket with me (in an urn).

But most of all, I just REEEEEEEEEEEEALLY don't want to die. The thought of it terrifies me.
