I don't think that's how it works. During A Court of Wings and Ruin, they were seperated by long distance, weakened, and Feyre was drugged with faybane. They mostly just used the bond to communicate; like when Tamlin went nuclear on his dining room and Feyre was injured. Feyre was also on the defensive for most of this time. Rhys didn't throughout the other books and didn't in this instance, slip into her motar control or vision, just her mind. The few instances when Rhys has seen inside her head, like when he asked about who she had used her magic on and saw Lucien, and vice versa, like what happend under the mountain, it was by mistake.
