Yes, there are quite a few. You can find some on popular fanfiction websites. Just search for 'Joey Tribbiani and Rachel Green love' and you'll likely come across some interesting stories.
A less explored but interesting theme could be how Rachel's pregnancy affects the group dynamics as a whole. Maybe the focus of the group shifts from just hanging out and having fun to being more about taking care of Rachel and the upcoming baby. It could also explore how the other friends' relationships change in the context of this new addition to their little family - like Chandler and Joey becoming more responsible uncles - to - be.
One common theme could be mystery. Since 'shadow face rachel' sounds rather enigmatic, it might be used to create a sense of mystery in the story. And when combined with an oc, the oc might be trying to uncover the secrets related to Rachel. Another theme could be friendship or rivalry. The oc could form a friendship or be in a rival relationship with Rachel, which would drive the plot forward.
One great fanfiction could be where Rachel Green's pregnancy is a turning point in her relationship with Ross. In this story, they might face new challenges and joys together as they prepare for the baby. It could show how their friends support them during this time, like how Monica helps with baby - proofing their apartment and Phoebe gives her unique parenting advice.
You can try websites like FanFiction.net or Archive of Our Own (AO3). They have a large collection of fanfictions, and you should be able to find some dedicated to Joey and Rachel's relationship.
Another theme could be humor. Fanfictions often use humor to lighten the rather risqué topic. The way Rachel reacts to the sex dream in the story could be really funny. She might be all flustered and her friends' reactions to her being in such a state could add to the comical element.
A friendship moment could be when Rachel is having a bad day at work and Joey just shows up with a pizza and some goofy jokes to cheer her up. They sit on the couch, eat pizza, and Joey tells her all about his latest audition disasters, which makes Rachel laugh and forget about her own problems.
Secondly, use euphemisms and subtleness. Don't be overly explicit. You can describe the dream in a more suggestive way rather than being graphic. For instance, instead of detailed sexual descriptions, you can say things like 'Rachel was engulfed in a passionate encounter in her dream, the details hazy yet the emotions vivid.'
