I believe the answer is:
'dreamlike' is the definition.
(I know that dreamlike can be written as surreal)
This is all the clue.
(Other definitions for surreal that I've seen before include "Disorienting and hallucinatory in appearance" , "Like Dada image, perhaps" , "Dreamlike - Dali-like" , "Dreamlike, irrational" , "Bizarre, fantastic" .)
