Ghosts are surprising things, by nature something we could never expect. What is real is perhaps novel or mysterious, fascinating or startling, but in some way expected. We can cope with it . . .
(I wonder if we dream at night because we lose so many things that we never knew we possessed but are cursed to watch them in brief and then disappear . . . )
Is it a blessing to imagine a world we will never inhabit?
Or do we rightly shed possibility for the here and now?
