Way higher than Himalayas, say, surreal (7)
I believe the answer is:
strange
'surreal' is the definition.
(I've seen this before)
'way higher than himalayas say' is the wordplay.
'way' becomes 'st' (abbreviation for street).
'higher than' means one lot of letters go next to another (some letters go above others).
'himalayas say' becomes 'range' (himalayas is a kind of range).
'st'+'range'='STRANGE'
(Other definitions for strange that I've seen before include "Odd, not familiar" , "Irregular" , "Odd, peculiar" , "Unusual, odd" , "Slightly odd, a bit weird" .)
