The Dreamer is a figure from Sith lore, specifically a Sith Legend.
The legend recounts the story of The Dreamer engaging in a duel against another Sith, known as The Monster-Slayer. The confrontation concludes with the demise of both combatants, as they succumb to the toxic fumes emanating from the Pits of Paxxis.
Luke Skywalker believed that the legend had a basis in reality, placing the events around 3400 BBY.
Skywalker eventually came into possession of an image portraying The Dreamer's battle with The Monster-Slayer. He added notes to this image, along with copies of The Jedi Path and Book of Sith, after the Emperor's demise, approximately in 11 ABY.
