The half breed and comic skeleton (Sans X Fem!reader)

7- Lets calm down

-Sans POV-

The party was sweet, I was soo tired. The sleep I had while I waited for (y/n) to finish her talk with her parents wasn't enough. These nightmares had had taken away the little sleep I use to have when I was underground. They have been had. I finally collapsed onto my bed and was just able to pull my blankets up before I was out. Then I felt myself falling, this wasn't like the normal nightmares I have been having. Everything was pitch black. I felt like I had been transported to a black void, like I had been sucked through a black hole. I felt myself land but my body felt like it wasn't right. I looked around but saw nothing but black until I saw (y/n) standing there, her back to me. I started to run towards her and called her name. She turned and then screamed and started to walk backwards. I came closer in hopes to see what the problem was, I was standing over her but she was shaking and tears were trailing down her face.

I went to reach down in hopes to help her but as I noticed my hand I saw they were bony claws. No my normal ones. I took a step back and stared, when I looked at (y/n) I saw she was laying down dead with a hole in her chest, where her heart would be. I looked at my claws in hopes it would disappear but instead I found them the same but bloody and a still pumping heart. I realized this was (y/n)'s heart and I dropped it immediately. I started to cry while repeating "no" over and over. She couldn't be dead. I couldn't believe this. I would never hurt her, never mind kill her. I turned in an attempt to run from this nightmare but I came face to face with a mirror. I was looking at myself, and yet it didn't look like me. I had sharp teeth with one on the left side gold. I had red eyes and they seemed dangerous. I had a black jacket with a red undershirt. I had black shorts but with a yellow line down the outside of each leg, I had black shoes with red socks visible.

I started to back away from this image. And expected to trip over (y/n)'s dead body but it had disappeared in the mirror. I saw the reflection's grin widen, like it enjoyed killing her. My tears were running none stop. In my anger I created a bone and smashed the mirror which oddly the reflection didn't copy. I fell to my knees and cried more while repeating no. this was a new nightmare; I never received this one before. I didn't like it; I never want to relive this again. I started to talk to myself in hopes that this would be over, "no, this isn't real. (y/n) is safe. She is not dead. But, but...... WHY!" I felt everything shake as I was shaking. Everything felt like it was falling apart.

Then the shaking stopped but mine continued. Then a voice of an old friend came, "Calm down sans. This is nothing but a nightmare. A dream created by a demon to make you weak and isolated. They wish to make you weak for their plans." I turned and stop shaking.

I smiled, "Gaster, dad. I am soo glad you are here. What do you mean?" he gave me a small smile.

He held out his hand for me which I grabbed as he hoisted me up like it was nothing, "sans, this demon has been sending you these dreams in hope to get your HoPe down, so you will be easier to fight and destroy. They wish to take over your plane of existence. For like me, they exist in many realms and planes of existence. They wish to gain more power to be able to do as they wish without any resistance. If they succeed in destroying your plane and engulfing all the souls they will have free reign in every other alternate reality. For you see there are many. Yours is named Undertale or Classic as others call it. The one who you saw in that mirror was a corrupted version called Underfell. That is a reality where monsters have a deep desire to kill, even other monsters. They have no problem killing; the one you have problems with that you call 'Flowey' actually helps the child get through. Now enough about that, there are many more examples but I shall not go into it. For it is your reality and plane I am worried about." This was a lot for me to take in. I might to try later to get more but I am willing to listen to him.

He gestured with his hands to follow him as he starts walking. I had to take many steps to match his long strides. He cleared his throat, "your one is a very interesting one. For starters, it is a slight combination of two. The main Undertale reality and another which I will not go into. This one is where Frisk has never reset or even killed but you are still aware of the named 'genocide runs' but even then, you do not push Frisk away but embrace them. Hence why Frisk staying in the underground till she was a teen. She has even been able to revive Asriel and to her age, Frisk is even an actual gender and not a confusion who which they are. It is something interesting. Now the demon believes that if they destroy this unique universe they will be able to take over all the others with the power that is in this reality. They are named 'Chara'. They have 'wormed' themselves into this universe when they aren't meant to be able to. They should not hold any power in this reality. Don't let them win; it is more than just your friends in danger. Oh and, keep the girl with you. I know she has deep feelings for you just as you have feelings for her. Embrace it; this will help destroy this demon. She will help controlling that ability of yours. Oh, also look after yourself. I have another reality to visit. Good bye sans. See you next time." And with that he was gone in a blink

I felt the darkness lifting. I felt myself wake up. But the first thing I saw was not what I was expecting. I saw (y/n) asleep right next to me with her arm over my body and her hand right on my spine. I felt my face heat up in blush as she woke up. Then her face went bright red and she started stuttering, "w-wait. It's not what y-you think."
