No longer in dreamland (5)
I believe the answer is:
awake
'no longer in dreamland' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for awake that I've seen before include "Completely conscious" , "Tossing and turning" , "No longer in the land of Nod" , "Conscious, aware" , "Unable to sleep" .)
