Float high in the sky (5)
I believe the answer is:
aloft
'in the sky' is the definition.
(I've seen this before)
'float high' is the wordplay.
'high' indicates an anagram (can mean drunk or on drugs and hence disordered).
'float' with letters rearranged gives 'ALOFT'.
(Other definitions for aloft that I've seen before include "up the mast" , "Above - on top" , "Animistic cult" , "In the rigging, up high" , "at high altitude" .)
