Fancy enough to seem perfect? (5)
I believe the answer is:
dream
'perfect?' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for dream that I've seen before include "Cherished desire" , "Illusion" , "It's experienced during sleep" , "Aspire" , "Cherished hope or ideal" .)
