Objects to disturbed nights (6)
I believe the answer is:
things
'objects' is the definition.
(I know this)
'disturbed nights' is the wordplay.
'disturbed' is an anagram indicator (the order of letters is disturbed).
'nights' is an anagram of 'THINGS'.
'to' is the link.
(Other definitions for things that I've seen before include "Items" , "Objects" , "Stuff" .)
