On a visible level, our body rots away and worms eat to our brain. On a smaller level, the molecules that make up our body become earth and nutrients and join the cycle of nature. On the particle level, we disintegrate "back" into the star stuff we are made off, our being from a universal perspective hardly changing (at least in the tremendous sense as we experience it). I find comfort in the last idea, that I am star stuff, destined to eventually move onwards to distant galaxies and infinite space, washing the shores of places unknown and beings unseen (thank you Carl Sagan).
Ghosts are as real as leprechauns and fairies or the God in Christianity, from a scientific point of view the probability of their existance in nature is close to 0. But the world we experience is in many ways not the same as what science tells us. Science tells me that my hand is at the same time attached to my arm, and floating at the other side of the universe. I don't experience this. Furthermore, science is far from explaining all the mysteries of the universe, it even seems that the more we know the less we understand about the most fundamental questions.
My father is an astrologist and his wife is a medium, they quite firmly believe in past lives and the continuity of life, ghosts and whatnot. I don't find that particularly disturbing. Perhaps what they experience can one day be explained fully by science or perhaps not, but I'm confident that the knowledge wouldn't make a difference in their every day life. Perhaps they'd have a brief "I told you so!" -moment but essentially their belief would remain the same. I treat their thoughts with curiosity, as I attempt to deal with all seemingly absurd or revolutional or funny or [enteradjective] thoughts that are foreign to me. I'm not a believer, or at least I try not to be.
