Finn and Rey end up force bonded where they can read each others minds/feel each other's emotions for awhile (maybe they touched some old Jedi artifact, or the force is trying to tell them something). It's a bit awkward and embarrassing as expected but it also shows Rey some of the awful things Finn went through as a stormtrooper and some of the negative emotions he still feels.
