Form of escapism where a clear head is lost in a blind alley (7)
I believe the answer is:
impasse
'blind alley' is the definition.
(synonyms)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for impasse that I've seen before include "Lack of movement" , "Inescapable perdicament, dilemma" , "Dead end" , "Situation of deadlock" , "hopeless difficulty" .)
