Like a haunted house (5)
I believe the answer is:
eerie
'like a haunted house' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eerie that I've seen before include "Strange and disturbing" , "spine-chilling" , "Uncannily strange" , "Spooky, macabre" , "Spooky, weird" .)
