Almost unconscious state (6)
I believe the answer is:
stupor
'almost unconscious state' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for stupor that I've seen before include "State of being stunned" , "State of shock" , "Shocked or drunken state" , "state of somnolence" , "Dazed condition as from drink or drugs" .)
