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.

Bo's Dreaming Of You is so named because of the cloud he eternally sits upon. He is very intelligent and strongly dislikes it when other Dragons tell him something he has to admit he doesn't know. Bo's Dreaming Of You enjoys dropping strange or tantalizingly legitimate daydreams into the minds of humans who pass by. One might say Bo's Dreaming Of You is a wicked, mean Dragon, but if one gets to know him and befriend him, he seems kinder than one thought before. One of Bo's Dreaming Of You's habits is dropping daydreams into his own mind when someone particularly annoying is speaking to him!
