Daydream Dragons are the hosts of daydreams and fantasies. They spend the majority of their time sitting on clouds, dropping daydreams down into the minds of people passing by. Humans who live near Daydream Dragons must be especially careful not to let their thoughts wander, or they could end up spending hours or even days in a trance-like waking dream state.

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 in Blue is a philosopher. He loves to stay high in the clouds, thinking about life and all those questions other dragons don't bother to think about.

He can be a bit boring, and gets annoyed really fast with noise and mess, being very prefectionist and loving peace and quiet. A bit selfish and cocky, thinks he's good just because he's smart and pretty, however he loves his daughter and mate and doesn't want to make anyone mad.

He often coments about the bad behaviour of Galgothe, and they don't get along very well, but as Dream in Blue spends a lot of time dreaming in the clouds, you don't get to hear them arguing a lot of times.
