Here os a brief plot synopsis of the 1991 film Begotten, from which that sreamy image was taken:
"The film opens with a robed, profusely bleeding "God" disemboweling himself, with the act ultimately ending in his death. A woman, Mother Earth, emerges from his remains, arouses the body, and impregnates herself with his semen. Becoming pregnant, she wanders off into a vast and barren landscape. The pregnancy manifests in a fully grown man whom she leaves to his own devices.
The "Son of Earth" meets a group of faceless nomads who seize him with what is either a very long umbilical cord or a rope. The Son of Earth vomits organic pieces, and the nomads excitedly accept these as gifts. The nomads finally bring the man to a fire and burn him.
"Mother Earth" encounters the resurrected man and comforts him. She seizes the man with a similar umbilical cord. The nomads appear and proceed to rape her. Son of Earth is left to mourn over the lifeless body. A group of characters appears, carry her off and dismember her, later returning for Son of Earth. After he, too, is dismembered, the group buries the remains, planting the parts into the crust of the earth. The burial site becomes lush with flowers."
