''After acquiring Lukana's body, she [Elluka] wields the ability to dream visions of the future due to the magic of the sin of Lust. Her visions show only images that she can recoginize. On top of that, her foresight's reliability is based on the "color" of the image. If the dream is "purple" then it is destined to occur and cannot be changed.''

Gammon Octo is known to constantly have purple dreams, often to help Ma write plays. Based on the paragraph above, I think the Purple Dream ability can be passed through the family and Gammon has it because Lukana's body had the ability as well.
