bad to the bone (Undertale sans x reader)

Nightmares

Your eyelids slowly opened, taking some time to get used to the bright light coming from the open window. 

To your dismay, there was no skeleton laying beside you. No note, no sweater....

 "Where'd Sans go?" You ask out loud, looking around.

You jump up from your empty bed and open your window, a burst of heat blowing into your room. 

It felt like a pretty hot day today, maybe the hottest of the year so far!

 But.....It was snowing last night.....

You ignore the fact that last night could've been a hallucination, since it's happened before,

Only until you realize something....not right.....

This wasn't your room

Or any room you've seen before....

You look around and go to the window once more to look at the view outside. The sky was a bright hue of baby blue, clouds frozen in place. A nearby hill in the distance stood proud. 

It looked all to real,

Until the sky began to glitch, twitching and flickering violently. 

You slam the curtain shut, turning away. 

 Too much junk food.....what did i eat last night?

You blink and watch as the posters on the wall disintegrated into mirrors, showing your frightened, sleepy expression, 

 "What the junk is going on?!" You ask aloud, walking to the bedroom door, not wanting to deal with anything else. 

You grabbed the golden knob and began to turn it. But it wouldn't budge. Your head began to pound and your adrenaline began to rush as you continued shaking the knob to the outside. 

Your mind began to rush and you began tearing up, kicking the door and pushing on it, in attempt to get the door off the hinges. 

 "Let me out!" You feel yourself begin to scream. 

Your energy was drained quicker than usual, and you fell to your knees, panting, your head spinning. You felt lightheaded and you groaned in pain, holding your head in your hands. 

 What is happening?

You refused to give up, determined to save yourself from this horror. You grab the knob and heave yourself up, stumbling to the bed you woke up on. As you reach the bed, you throw yourself upon it, panting and sweating. 

 "Why am i so weak?" You ask yourself, pressing your thumb against your wrist to check your pulse. 

As you did so, you felt a sharp sensation in your arm, making you yelp in surprise. You focus on your veins in your arm, barely visible, but usually blue and string-like, as usual. 

Your veins were a vibrant neon green color, and you could feel the foreign substance flowing into your body. 

 "Who injected this?" You ask, sitting up on the bed. 

At least....you tried....

You found you were strapped to a medical table, legs and arms wide open and apart. 

 What kind of kinky shit is going on?!

You struggle to break free, but you found with every move you became weaker, the substance inside of you becoming more extreme. 

 "Help...." You groan. 

You close your eyes, your eyelids becoming weaker with every breath. 

A deep chuckle filled your ears, sending chills up your back. 

You slowly gain all of your strength to open your eyes, and what you saw before you....

Was something out of a nightmare
