I think there are many layers to this answer. Personally I do not believe in the afterlife as a physical place, I more see it as a pool of endless dreams. I also have a place within all of this I call the sea of forgotten memories, here we can drift without any conscious disturbance; just be left alone for the ages to drift by us if needed. If I should put an image on it I kind of think of the words of Gandalf the White: "Darkness took me, and I strayed out of thought and time". Personally I look forward to one day drift into serenity and get born anew.
