When cycling, green light turns … same old story! (4,2)
I believe the answer is:
deja vu
'story' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for deja vu that I've seen before include "Unoriginal material" , "Feeling of repeated experience" , "Unpleasant familiar illusion" , "strange experience?" , "Feeling one's experienced a situation before" .)
