Canter around in a state of abstraction (6)
I believe the answer is:
trance
'a state of abstraction' is the definition.
(I've seen this before)
'canter around' is the wordplay.
'around' indicates an anagram.
'canter' is an anagram of 'TRANCE'.
'in' acts as a link.
(Other definitions for trance that I've seen before include "Deep sleeplike state" , "Hypnotised state" , "Catalepsy" , "State of a medium in a seance" , "Canter into hypnotic state" .)
