When Two Fates Intertwine (Sans x Reader)

Dreams and Nightmares

~Your Perspective~

You wake abruptly in the middle of the night, bitterly cold. You blink in confusion, trying to recall where you are. The room is more visible than it had been earlier, bathed in a royal blue light. You note the scattered socks and ketchup bottles, slowly relaxing as you recall the events of earlier.

I'm in Sans' room. But why is it...?

You glance over at Sans, a sinking feeling settling in your gut. He's erratically tossing in his sleep, fists clenched and body covered in sweat. His shirt is soaked through in spots, the mattress damp underneath you. A sheen of it covers you as well, and without his warmth, it has you absolutely freezing.

But none of that matters right now.

His face is contorted in what looks like fear, his bone brow furrowed and characteristic smile pulled tight to the point of looking painful. His magic dances under his closed eye socket, a trail of royal blue weaving in the air as he tosses and turns. His breath comes in pants and he cries out, the panic emanating from his soul causing your own breath to catch in your throat. You can only imagine what he's experiencing.

"Sans!"

You immediately go to wake him up from his nightmare, your hand clasping his slick shoulder, when you hesitate. You can almost feel the scar on your own shoulder aching. The last time you'd interrupted one of these episodes, the result was several stitches and Sans almost killing himself.

"Shit," you mutter to yourself, drawing back.

What am I supposed to do?! For all you know, Chara is in his head right now, tormenting him. In fact, after seeking her out yesterday, you'd been expecting her to give you a sleepless night. If targeting Sans is her way of getting to you... it's working.

As you watch, sick with worry, you notice a second royal blue glow shining through his shirt. It flashes erratically, waves of panic and despair reaching your soul with every pulse.

I know this glow. You watch for a few more seconds, making out the barest trace of an upside-down heart shining from within his chest. You feel as if his panic is about to swallow you when a sudden calm washes over you. Wait, I've got it!

You're filled with DETERMINATION.

You summon your soul out of your chest, its sky blue light solid and calm amidst the desperate dance of Sans'. You take a deep breath and close your eyes, focusing on your necklace. On your connection.

Immediately, your calm is shattered. Your breath shudders in your lungs as you gasp for breath, a heavy weight settling in your chest. It's both familiar and overwhelming, bringing you back to a point several years ago where panic attacks were commonplace for you. You dig your nails into the skin of your arm, willing yourself to push through it. You're hardly scratching the surface of what he's feeling–you can sense it.

It's not enough. I need to go deeper. The glow of royal blue intensifies and rises behind your closed eyelids. You're struck with the urge to open your eyes. To look, and see the essence of all that he is. Your soul aches with the desire to see him, know him. He promised he would show me. It will be on his terms; for his sake.

You grit your teeth and push the feeling down, focusing entirely on your connection as your soul reaches out for his. The light of your soul dims until you can no longer distinguish what light is coming from where, the rhythm of your soul matching his beat for beat. A wave of chaotic emotions crashes into you, emanating from deep within him. It washes over you and sweeps you away, pulling your head underwater and stealing the breath from your lungs.
