I don't know where you got the impression they are strictly logical. The Dreamers have emotions, all animals have emotions. All animals feel pain, anger, sorrow and loss, it merely is to the degree that the animal is self-aware enough to understand is the question. Any intelligence that may exist in the universe in all likelihood has some form of emotive capability even if we can only speculate on the extent of those emotional displays. Emotions in other species are viewed as an opportunity to understand and define the emotional parameters of said species. All of this is done to understand their capacity and limitations much like modern researchers conduct studies on animals today. 

Skallagrim conducted a social experiment with you. Your character is what would be considered a verbal bully of the six defined bullying categories. Talking about someone in a manner that is disrespectful and in many cases hurtful. While you insulted the Queen and that is a punishable offense to the Dreamers hearkening back to a time prior their ascension. The first thing was to understand your psychology. Your actions whether an attempt to save the man, to allow him to be killed or to surrender yourself in self-sacrifice was what needed to be seen.

From your actions the Dreamers begin to place you in an ever refining category until they have enough information that they can store your dream fragment in the dark records.

Thus in our fight Skallagrim will record your actions and reactions, looking to see if you employ any stratagem in your actions or simply react and try to over power your opponent. 

Dreamers are merely observers and recorders of information to be disseminated and studied by those in Slumber. Unless you are drenched in Galdhr energy they only mark your passing. If there is something unique and different then they will take more than a cursory notice of you. Watching from the shadows or if piqued enough they will approach the being or civilization.
