Stupefied, two metres apart perhaps? (6,3)
I believe the answer is:
spaced out
'stupefied' is the definition.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for spaced out that I've seen before include "Separated" , "High on drugs" , "Placed well apart - unaware of one's surroundings" , "Disorientated through drug use" , "affected by drugs" .)
