Here's the final image in the series and I thought this article written by
fascinating. It describes the analysis of seafarers dreams. When on land they they tend to dream of blue skies and calm seas, but when at sea they dream of maelstroms, sea serpents and raging storms. Published today in The Times T2 section, here's a snippet....
"At sea, a sailor’s slumber is overrun with nightmares; but when his trick is done, and he is back at home in bed, then his nights are filled with dreams. This is an axiom well known to all who sail: that out there your sleep is ruined by unconscious fear, but back here is made bliss by the nocturnal pleasures of remembrance and longing."
