Kirk seems like the type of person who would go through phases of different ways of life. In an earlier episode, Kirk stated that he couldn't drink coffee and in another, he stated that he didn't like dogs. Obviously, these two statements are false as we've seen him drink coffee and be a dog walker. The "night terrors" thing was probably along the same lines, as he has also slept in the town square.
