Like a foggy graveyard (5)
I believe the answer is:
eerie
'like a foggy graveyard' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for eerie that I've seen before include "Bloodcurdling" , "Unnerving" , "Weird and disturbing" , "Spectral" , "Frighteningly odd" .)
