sleep

   to be dead

   While you await the resurrection of the body.

   Often in compounds according to the circumstance.

   Thus to sleep in your leaden hammock or in Davy Jones's locker was to have died and been buried at sea:

    Though Drake their famous Captain now slept in his leaden hammock. (Monsarrat, 1978)

   To sleep in your shoes was to be killed in battle:

    The dreary eighteenth day of June

   Made mony a ane sleep in their shoon;

   The British blood was spilt like dew

   Upon the field of Waterloo. (G. Muir, 1816)

   When F. D. Roosevelt died, the official White House statement said he had slept away, which did not refer to yet another overnight absence from Eleanor with his mistress at Mount David:

    The four Roosevelt boys in the services have been sent a message by their mother which said, 'President slept away this afternoon'. (Ranfurly, 1994 — 1945 diary entry)

   Sleep is death:

    Anyone who went to sleep in a dug-out where there was not much air with one of those fires going... would soon drop into a sleep from which there would be no awakening. (F. Richards, 1933)
