Night of the Living Nightmare is the forty-ninth episode of Ben 10: Ultimate Alien.
Ben is asleep, but is rudely awakened by a Cassiopeian Dream Eater, which immediately latches itself to his face. He struggles against it, but his panicked cries are muffled by the creature and he collapses from near-suffocation as the creature's influence begins taking hold. Ben gets a second wind and transforms into NRG to battle it. After seemingly killing it and transforming back into normal, Ben starts watching TV. Only static comes on and Ben unplugs it, only for it to stay on. Ben checks the rest of the house, but a DNAlien attacks him. Ben transforms into Four Arms and defeats the DNAlien. However, it disappears when Four Arms' attack destroys the house of his neighbors. When Ben looks and realizes that they are not there, he calls Gwen followed by Kevin, getting no answer both times.
Then, Vilgax appears and destroys Ben's car. Ben transforms into Goop to fight him before transforming into Spidermonkey, then Ultimate Spidermonkey. Then, Vilgax gets hit by a truck without a driver and he disappears. Ben decides to go to see Kevin in person. When he arrives, he doesn't find Kevin. Aggregor appears and Ben transforms into Lodestar to fight him, only for Aggregor to disappear.
Ben takes Kevin's car and goes to Julie's home, where Ship merges with Julie and starts to attack Ben. Then, Ben transforms into Eatle and fights back only for them to disappear as well. Ben drives through a forest and sees a man hitchhiking twice. Ben ignores him and continues his way, but then he looks into the mirror and sees Hex inside his car. However, when Ben turns, Hex isn't there anymore and he appears on the road. Ben, trying to avoid him, crashes into a tree.
Gwen and Kevin show up, asking Ben to give them the Ultimatrix, wanting a turn. Not believing them to be themselves, Ben transforms into ChamAlien and runs into the forest. Gwen uses her powers to track ChamAlien, then Kevin absorbs the Ultimatrix, transforming into Ultimate Kevin, and Gwen appears in her Anodite form. Ben transforms into AmpFibian and shocks Ultimate Kevin, causing him to faint. Gwen believes AmpFibian (after he transforms back into normal) killed him, and tries to convince Ben to take off the Ultimatrix. Ben transforms into Swampfire and uses seeds to trap Gwen. Ben guesses that she is actually Albedo and that his experiences are a kind of induced dream. After revealing his true form, Albedo transforms into Fasttrack and runs off. Ben transforms into Fasttrack as well and goes after Albedo.
Ben goes to Mr. Smoothy and is attacked by ChamAlien. Albedo then transforms into Big Chill, attempting to freeze Ben, but to no avail, as Ben's knowledge of being inside a dream makes him invincible in it and immune to Albedo's attacks. He then transforms into NRG, only to be pulled out of his containment suit and then Brainstorm, but is again defeated. Albedo stops using aliens and attempts to reattach the Dream Eater on Ben, but he slips on a smoothie, and the Dream Eater falls on him. The scene shifts to Ben's bedroom, where the real Ben, Gwen, and Kevin are. Albedo had never attached the Dream Eater to Ben at all. He had slipped on the same Mr. Smoothy in Ben's room and the Dream Eater attached to him; the entire episode thus being Albedo's nightmare. Gwen explains that the Dream Eater feeds off the chemicals produced by the brain during stress and traps the host into a nightmare. Ben asks whether they can simply pull it off of Albedo, Kevin reveals that they can't without ripping his face off along with it, but suggests a Galvan doctor could. Gwen reveals that she already called, and that a plumber transport is on the way.
The episode ends with several Ultimatrix aliens confronting Albedo in his nightmare.
