Sleep is a gift, a gift beings take for granted. When you sleep you dream and when you dream you're taken out of the waking world to a state where there is no pain, no emotion, everything is not what it seems. Time flows around you but you stay the same. In his youth Anakin Skywalker feared sleep; visions of pain, suffering and death haunted him all his life taking away those he loved. Now Darth Vader he longed for it. to sleep to escape from his shell to escape this cruel destiny in which dreams were the cause. the few times he was able to sleep were the happiest he'd ever allow himself to be since he was transformed.
Darth Vader dreamed. in his dreams he was young again as he was; free from his prison free from the dark side, he was young and running through the fields of Naboo running after...Her
She often came to him but they were mostly flashbacks, others were wraiths of guilt and accusation. This one was recurring, he was running after her and she was always just out of his reach. He could see her emotionless face, her long hair flowing with flowers, clothed in blue robes her hand outstretched towards him clasping a necklace. This was his dream and he always woke having never caught her.
This time however was different, he passed over a hill and the landscape before him changed. Padme disappeared entirely; the landscape before him became a wall of shimmering light, the wall came closer to him until it engulfed him a tunnel formed in the wall and images appeared at the other end. It was a force vision he hadn't had one since....
The image was one most unexpected: His son Luke he was screaming in pain "Father please help me" he screamed the image morphed from Luke to an all too familiar image: The horrible visage of Palpatine he too was writhing in pain wreathed in lightning. the imaged morphed again. this time to....Anakin Skywalker?
"Lord Vader" the dream disappeared and his vision returned to that of the infrared and hud displays of his mask he was sitting crossed legged in his hyperbaric chamber and he was aware of his breathing " Yes Jerrjerod what is it?" The Moff swallowed hard he knew he must have interrupted something important "The Emperor's shuttle will be arriving shortly sir." Jerrjerod was met with breathing "Thank you commander" Jerrjerod bowed and left leaving Vader alone. He pondered the vision he just had; taking everything into account he weighed the life of his son over the Life of his master, too evenly matched taking into consideration what happened with Padme he decided....to do nothing whatever happens would happen after all it was the will of The Force.
