Have dreams (6)
I believe the answer is:
aspire
'have dreams' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aspire that I've seen before include "Set your sights on" , "Have a strong desire to reach an objective" , "Have ambition or desire for praise" , "Strive for higher things" , "Have a strong desire to achieve something" .)
