Red Dragons are similar to typical story book dragons. They shoot flames, can fly, etc. However, they aren’t evil creatures as depicted in myths and won’t go around raiding castles, killing knights, or kidnapping princesses. They live in a variety of habitats, from forests to coastlines to abandoned castles, usually in warm climates, and eat whatever living creatures they can find.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Dream Slayer cannot enter other's dreams. He does talk in his sleep and sleepwalk as well. Dream Slayer gained his name due to his violent tendencies in his dreams that get expressed in the real world. Sometimes, he says names of particular dragons in his dreams, mostly either Night or Astral. He has mentioned Night and Astral numerous times so some event will happen between the two.
