I dream foolishly, love (6)
I believe the answer is:
admire
'love' is the definition.
(thesaurus)
'i dream foolishly' is the wordplay.
'foolishly' is an anagram indicator.
'i'+'dream'='idream'
'idream' with letters rearranged gives 'ADMIRE'.
(Other definitions for admire that I've seen before include "Goggle at" , "Regard with respect and approval" , "Esteem, look up to" , "Respect (someone)" , "like very much" .)
