Today, thinking of Belgrade, the trams down King Alexander, past Vuk's spomenik (which, I think, is an ironic name, as the pedestal is very different from your average spomenik), and down to Parliament Square. On my last visit, before heading out to Zemun for a bit, I had a place a few doors down from the church, very convenient to Sbux and the JDP. Perhaps my spirit is wandering abroad.
Travelling around and sleeping in many different places, I have frequently had the uncanny sense of encountering people or spirits distinctly from that place (micro-place -- that hundred yards or so) in my dreams. (St. Mark's proximity to those Belgrade rooms might have informed a few dreams as well.) I have no idea--if they are mind-independent to some degree--whether they are the living of the place or the dead.
More things in earth and heaven. Particularly in the bits in-between.
