Hypnotic state (6)
I believe the answer is:
trance
'hypnotic state' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for trance that I've seen before include "Dream state" , "Sleep-like state experienced in canter" , "Canter into hypnotic state" , "Mesmerised state" , "Canter about a daydream" .)
