Haunted house noises (5)
I believe the answer is:
moans
'haunted house noises' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for moans that I've seen before include "Mournful sounds" , "Grumbles" , "- - and groans" , "Complains" , "Trivial complaints" .)
