Morpheus.
Morpheus, also known as Somnia, was the Greek God of Dreams, the one with the amazing ability of appearing in dreams of mortals in any form.
Morpheus was the god responsible for the dreams of people. When in the arms of Morpheus people would enjoy a sound sleep, but would also see dream about their future or even coming events. Morpheus was the dream messenger of Gods, communicating the divine messages through images and stories, created as dreams. He also revealed to be an aspect of Dream whom is a member of the Endless.
Being the master of dreams, Morpheus had the ability to send images to the visions of people, to shape these images and give a form to the creatures that lived in dreams. Morpheus himself had a talent in mimicking any human in the dreams, and was able to take any form he wanted.
When in his real form Morpheus had wings on his back. It was believed that he and his brothers were given wings by their uncle Thanatos, the deity of death, although some interpretations said that they were wing-born. The legend says that Morpheus used his wings not only to reach those who needed help in their dreams but also to carry his father, the wingless Hypnos, to the dream world in the caves, when in several occasions needed to be saved from Zeus’ menace.
