A strange new gem has put the Crystal Gems into a never ending nightmare and only Onyx and Amethyst can save them.


The episode starts off with Amethyst running from something in the Kindergarten. A group of evil gems chase after her and she tries to hide. She unfortunately got spotted and tried to run again. She then tripped on the ground and was about to be killed by the gems. Then suddenly, she woke up in her room revealing it was just a horrible nightmare. She tries to go back to sleep but she is plagued by the nightmare. She then walks out of her room and goes outside for a bit. She looks at the moon and see it now eluminating a blue color from it. Then she hears the door open and Onyx comes outside. Amethyst asks him why he was outside in the first place. He told her that he just wanted some air. Amethyst told him about the nightmare she had and then looked up at the moon seeing its blue glow. He tells Amethyst he knows whats going on. He explains that a gem is causing the nightmares to happen and that if they don't wake them up by the end of the night, they will be stuck in their nightmare forever. They run in the house and drag each gem into the living room trying to get them together. They do that and Onyx draws with black chalk a symbol one side representing dreams and the other nightmare. Onyx explains that they need to go into the dream realm to save them from the gem. They hold hands and begin to fall asleep into the Gems' dreams.

They first enter into Steven's dream where they see him and Lapis on the beach. The two are about to kiss but something happens to Lapis. She begins to change her personality to a violent and evil side making her attack Steven. He runs for his life, trying to escape but it doesn't work. Amethyst asks how are they going to stop Lapis. Onyx tells her in the dream realm anything can happen. He jumps out and blasts a black beam at Lapis which reveals that it is a shard of moonstone and retrieve it. Then Lapis appears and goes to Steven comforting him from what happened and gives him a kiss, restoring his dream. Onyx then creates a portal to the next dream which lead to Lapis Lazuli's dream. They go into a room with a cage in the shape of a mirror with a giant Peridot and Jasper tormenting her. Amethyst told Onyx she will take on Peridot while he takes on Jasper. They then grow into massive size equal to the size of Peridot and Jasper. Amethyst and Peridot go into battle which ends with Peridot being tied up with Amethyst's whip. Onyx and Jasper go into battle and with a blast from his ray of nightmares, he defeated Jasper. The two then disappeared leaving behind two moonstone shards. They return to regular height and unlock the cage, freeing Lapis. With her free, Onyx makes a portal that lead to Emerald's dream.

They enter into the dream and see Garnet trying to attack Emerald but he refuses to fight. Amethyst notices that the gems on Garnet's hands are the color of the moonstone shards knowing that she had to be stopped. Onyx then created a form of Garnet that acted and looked like the real one. The evil Garnet keeps fighting but then the Garnet that Onyx makes beats the evil one leaving behind a moonstone shard they needed. They then see Emerald and Garnet flirting with each other showing the dream was restored. Onyx then creates a portal again which takes them to Garnet's dream. They see Garnet on the beach fighting against a army of red soldiers, they saw from the spaceship when they saw Ruby. She constantly tries to fight but it becomes overwhelming and she begins to attacks. Then Onyx uses his staff to create a black hole to suck all the soldiers into it and makes it disappear. Suddenly, a massive ship approaches and starts attacking them. Amethyst fires a short from her whip which destroys it leaving another moonstone shard which they take. The dream was restored and move on to Rose Quartz's dream with a portal. They see Rose Quartz looking for Steven which he was no where to be found. They hear Steven screaming for help but Rose cannot find him anywhere in the darkness. Amethyst summons a torch and brightens it up for the room to eluminate. Rose then sees Steven locked in a cage which Rose manages to get him out and hugs him tightly. The cage then disappears leaving behind a moonstone shard which they take. They were halfway there with fixing the dreams so they continued through a portal that lead to Pearl's dream.

They go into a room were they see Ruby and Sapphire fighting Pearl joins in the fight but suddenly Ruby slashes Sapphire across his face making him collapses to the floor Amethyst snare her with her whip and Pearl slices Ruby which leaves a moonstone in her place. Pearl goes over and begins to cry for losing Sapphire. Onyx, however, heals him with his dark magic and restores him to normal. Pearl then hugs him tightly which restore the dream to normal. They then make a portal and make it to the last dream which is part of Sapphire. They see Ruby sitting on a throne with Pearl in a hanging cage above a vat of boiling lava. Sapphire bursts into the room and summons his scythe to rescue Pearl. Ruby and Sapphire go into battle and Amethyst sees this as a chance to free Pearl. She walks over to the cage and avoids detection and frees Pearl from her cage. She then wraps her whip around Ruby and Sapphire uses it to slice her leaving the last moonstone in her place. Pearl then runs over and kisses Sapphire which opens a portal back to the real world.

They wake up and see that the others begin to wake up from their dreams. They don't know why they were there so they all just went back to bed in their rooms. Amethyst and Onyx however go outside and take out the moonstone shards they got in the dream realm. They lift it up to the moon and the shards begin to fuse together and form a gem. She landed in front of them and thanked them for restoring her to normal. Onyx asked why she was causing nightmares to the gems but she told him it was unintentional. The shards from her shattered gem into their dreams changing them making them into nightmares. She then asked for their forgiveness for causing the problems and both agreed to forgive them. She thanks them again and levitates of the ground and travels back to the moon. They then went back to bed to get some real sleep. Onyx feel to sleep quickly but had a nightmare about him turning evil again and killing all that he loved. He woke up and looked out the window to see if the moon was glowing blue again showing that Moonstone gave him the nightmare but it was normal. Amethyst then entered the room and told Onyx she had a nightmare again and asked if she could sleep with him for the night. Onyx began to blush and told her she could. She got under the blankets and snuggled with each other as they fell to sleep.
