Séance state (6)
I believe the answer is:
trance
'seance 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 "kind of altered state" , "Dazed state" , "Nectar (anag)" , "Canter into one of these at a seance" , "state of shock" .)
