Nightmare X Reader {she's mine}

What happened to you?

Nightmare went inside and went to Dream, "still thinking about her?" Nightmare asked, Dream sighed. "Yes, it was so sudden!" Dream said, you hated that you had to be at Nightmares side the whole time he talked about the tragic death of you. "Nightmare, I did find a possible way to get her back alive," Dream said looking positively at Nightmare. Nightmares eyes widened as he coughed trying to appear fine, "r-really?" He said trying to also look happy and excited to see his "mate" come back. "Yeah! Reaper has the dust! And he said it won't be any trouble so!" Dream said excitedly. You could see Nightmares eye twitch, he was getting mad really mad for something, this was to much to take in for you. "Nightmare, you Alright?" Dream Asked his smile fading a bit. "Y-yeah, I'm fine! Just thinking about when I see her again!" Nightmare Said putting a fake smile on. "Great!" Dream said. Dream soon got a phone call from Ink, so he stepped in the kitchen for a while. Finally, a time to talk with Nightmare. "What has gotten into you?" You say putting your hand on his shoulder. "Nothing has, I just don't want you to leave me," Nightmare said turning around with a...devilish look. "And we don't want you to leave me? Huh?" Nightmare said fully turning around to you. You looked at him in disbelief, this isn't Nightmare at least a side you haven't seen before. "Nightmare what's wrong?" You ask him, he just laughs, "There's nothing wrong, in fact this is me, your good old Nightmare." You whisper to yourself 'well heck yeah a Nightmare' "what did you say?" Nightmare says looking at you cringing madly. "Oh nothing" you say looking frustrated. Nightmare looked at Dream as he ran out the door holding his staff. Nightmare stared at the door as Dream shut it quickly. "Nightmare~" you say snapping your fingers to get him out of his little day dream. It just makes Nightmare stare a little calmer, "I know what he's playing at!" Nightmare said smiling. "And I hope I don't know what your playing at!" You say. Nightmare goes upstairs into his room, you follow him, floating behind him? He locks the door behind him, great, Still following him. You could see him look in a drawer and find some kind of.....oh! You know what it is! Wait....that's poison! He might be trying to poison Dream! "NIGHTMARE LISTEN TO ME? ARE YOU OUT OF YOUR MIND?" You yell but all he does is put his finger to his mouth and say, "shhhh! Don't worry, in fact you cant do anything can you? So you shouldn't be worried!" Nightmare said. "Well....what if I want him alive!" You say, that only makes him more mad. "Well he won't after what you just said!" Nightmare says slamming the poison back in the drawer. "B-b-but I really want him to..." you say but Nightmare cuts you off, "SHUT UP! YOU ARE MINE AND ONLY MINE NO ONE CAN HAVE YOU ACCEPT FOR ME!" he yells making the whole tiny house shake a little. You look at him, scared for your and the others lives, even tho you where dead Nightmare could abandon you at any second and you would be basically actually dead. All he does is grunts and then looks like he's got a plan, oh no, it's gonna be to kill Dream! Isn't it!? You grab for the poison, but still your mostly like a ghost, it goes right through you. Ghost like tears fall from your eyes as Nightmare looks back at you., he starts sprinting to the kitchen to poison the dinner that Nightmare was making for Dream and him. You yell at him the whole way to stop and think, "Dreams not dumb! He won't eat it!" You would yell. But still he doesn't answer.

The whole rest of the day Dream was gone and you where just sitting by Nightmare, thinking about what Nightmare actually do to everyone, poison them? Strangle them with his tentacles? Stab them? Would they even hurt them at all? After Dream came home you where a flood, tears dropped down from your face from every thought that came to your mind now. And then the moment came, dinner. Dream thanked Nightmare for cooking for once, Nightmares just stared at him take the poisoned food, cackling a little to himself time to time. You told Nightmare to stop him from eating it. He just looked in your direction and smiled even wider and even once he whispers to you "your mine now! Got it?" You slowly nodded and sobbed in your hands as Dream ate. "Thanks again Nightm-" Dream passed out, not died but just passed out. You looked up at Dream and then Nightmare and then Dream again. Nightmare stood up and took out a tentacle near Dreams skull, and he got closer, and closer, and "Hey Dream I'm here! Now what did you want to talk about?" Blue said opening the door, quite rude to not knock tho, but that didn't matter, he basically saved Dreams life. Nightmare put his tentacle back behind him and teleported upstairs. You exhaled "thank you Blue, thank you!"
