"Field of Dreams" state (4)
I believe the answer is:
iowa
'field of dreams state' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for iowa that I've seen before include "State of USA" , "part of United States" , "'Hawkeye State'" , "Midwest US state" , "US state, capital Des Moines" .)
