I once had a brief dream in which Rider was my servant. I was getting ready for class as usual, and she was protesting, expressing concern for my safety. I reasoned that I would be back long before sunset, and even if someone were inclined to attack me, there are literally hundreds of witnesses nearly anywhere on campus.
Of course, not being a magus I couldn't allow her to take a non-physical form, so she had to stay home, or so I thought. She insisted on coming with me, even sat in on my classes, which I had to try to explain to my professors.
Still, taking her around, showing her things, having lunch together, it was nice.
Then I woke up and had to go to class alone.
