Especially since you know you'd have to sit through another dissertation on which of your cousins are married and which ones are getting divorced. A woman with such a head for names and dates missed her calling in the community college history department. I don't think so. One thing we can count on, among the living, is that threats of noises in the dark are not going to significantly change our behavior. We might play our music a little louder, or make our fires a little brighter, but if we've made up our minds to do something, a few scares, even from legions of dead, will not alter our paths.
Humans are notorious for continuing on, even into the face of certain destruction.
Phantoms and spooks are enough to unsettle our sleep a little, but not enough to put us off our course. Since I'm not dead, this is all just conjecture, of course, but it seems to me that being dead gives one the leisure to think things all the way through. I think we'll all see that, even if physical movement and action are possible, it will be patently obvious that they are also pointless. No, if you want to change anything in the world, you'll need to do it while you're breathing. You had your chance.
