I believe the answer is:
nebulous
I believe this clue is a double definition.
'vague' is the first definition.

'hazy' is the second definition.

(Other definitions for nebulous that I've seen before include "Indistinct and vague" , "Hazy and cloudlike" , "Cloudlike; vague" , "Cloudy; hazy" , "Cloudy or indistinct" .)
