All At Sea

Meaning:
In a state of confusion and disorder.

Origin:
This is an extension of the nautical phrase 'at sea' and dates from the days of sail when accurate navigational aids weren't available. Any ship that was out of sight of land was in an uncertain position and in danger of becoming lost.
'At sea' has been in use since the 18th century.

"We don't navigate
by the same chart.
It's spring
and I am floating all at sea
in my coracle
down
the flood
of remembrance
- your long legs leaning
against the wall
of the old house
with the whole moor
flying in the mist."
