Run in strange trance (6)
I believe the answer is:
canter
'run' is the definition.
(I've seen this before)
'strange trance' is the wordplay.
'strange' indicates anagramming the letters.
'trance' anagrammed gives 'CANTER'.
'in' is the link.
(Other definitions for canter that I've seen before include "Horse movement seen in trance" , "(Horse's) pace between a trot and a gallop" , "Horse gait quicker than 9 across" , "Gallop easily" , "Ride at a quick pace" .)
