Dreamlike (7)
I believe the answer is:
surreal
'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" .)
