Woman "in my dreams," in song (5)
I believe the answer is:
irene
'woman in my dreams in song' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for irene that I've seen before include "US actress, -- Dunne" , "In Greek mythology, the goddess of peace" , "Greek godess of peace" , "Peaceful girl" , "woman" .)
