Cretan disaster stunned state (6)
I believe the answer is:
trance
'stunned state' is the definition.
'trance' can be an answer for 'state' (trance is a kind of state). I am not certain of the 'stunned' bit.
'cretan disaster' is the wordplay.
'disaster' indicates an anagram.
'cretan' anagrammed gives 'TRANCE'.
Can you help me to learn more?
(Other definitions for trance that I've seen before include "Exalted state" , "Sleep-like, half-conscious state" , "Canter into one of these at a seance" , "Sleep-like state perhaps induced by hypnosis" , "Ecstasy" .)
