In the dark of the night there is more room for mysticism. Everyday life is robbed of its pace, we sleep and dream and are less alert. This is the time of which ghosts make use to pass us by; on their way from the unknown to the unknown.

Moonlight is reflected in shallow, rippling coastal water, but everywhere else it is so dark that all things remain colourless. We hear soft, faraway sounds from the coast, such as, a ship's bell and some vague mooing. Perhaps we see the contours of a motionless bird against the silvery reflections. Then the animal slowly spreads its wings and flies away. In mythology, such a visit is traditionally a bad omen.
