Grey instead of black

A divergent one shot about Tris's whole dauntless experience simply being a dream, but maybe so much more than that. She soon starts realizing, it may have been a glimpse into her future

I had this idea and was thinking
"I still have a ton of other fanfic I would rather do right now."
But then I was like
"Wait! I CAN DO A ONE SHOT!"
So here I am!
This is my first one shot and I hope my idea is different from other people's.
