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.

Dreaming Dusk is one of the "first" newer dragons to be born in the cave. It gives her a fairly high status. She has Colorless Frost as her mate. The other dragons don't go near her often, as she wont listen unless it is important. Sometimes, she will do work as well, but only in a time of crisis. Dreaming Dusk is known to have a temper, and Colorless Frost is the only dragon that can keep calm and wont lose his temper at her, so he is a suitable mate for Dreaming Dusk.
