I think Jason had a nightmare in the New52 run after being attacked by the Joker. Ducra was in the dream too but I can't remember if she was just part of the dream or if she really was there.
And there are some fanfictions about Jason having nightmares.
Here's one I was able to find quickly:
Animal Magnetism by Badwolf36
Maybe the fanfic is already on the list of recommended fanfics in the OP but it doesn't hurt to link the story one more time.
It's a cute oneshot with Jason, Damian, Alfred the cat and Titus.
