*I know requester wanted the cross one, but they also requested this at the same time. So I wanted to make it after the cross one but then I had request to finish. Sorry that this one was late! I'm open again for request, just leave them on the requesting page, I'll write them down then make them. And if you guys have any plot ideas please let me know!

Warning: goopy nightmare, Yandere, stress, not being able to sleep, dreams becoming real.

×takes place on surface×

The medow was warm today, a calming sunset surrounded you, flowers blew in the wind, birds chirping, butterfly's flying all around you, and a flower crown on your head.

You wore a beautiful ivory dress that went to your knees and swayed in the wind as did your hair.

It was such a shame.. why couldn't your dreams be more like this? Oh that's easy, because an actual living nightmare stalked you.

You didn't know what he wanted, but he would always appear in your dreams and scare you, wrapping those long tendrils around your waist pulling you close to him.

He would pin you with a large smirk, black ink oozing off of his face, but you would wake up before anything happened.

You shake your head. Maybe.. he wouldn't arrive this time.. maybe he'd leave you alone..

It seemed as if life wasn't in your favor, the sky's went dark, thunder echoed around you, the birds turned into crows screaming, the butterflies died, the trees were on fire.

An intimating voice sent shivers up your back, he spoke with a Possessive tune.

You yelp and try to get away so you could wake up, but shackles kept you in place, the chains were too heavy.

He walked slowly, taking his time with each step, his chuckle filled the silent meadow.

You fall to the ground crying into your hands.

Two tall figures picked you up from the arms and dragged you to the nightmare himself.

He laughs. "Thank you, now get out. I need to talk to my little insomniac."

The figures nod and toss you harshly on the ground at his feet.
He smiles down at you, one of his tendrils lifting your face to look him in the eyes.

He smirks at your face, and licks the tears away. "Hush my little insomniac, Nighty's here for you!"

You close your eyes and more tears fall,making him frown.

"Y/n... Look at me now."

You open your eyes still crying.

He looks into your eyes sympathetically and he releases you.

You land on your knees.

His gaze still lingers on you. He sighs and falls to his knees and hugs you.

"You're afraid of me.. arnt you?.. y/n, I never wanted to hurt you.. but this is the only way I can see you.. until I figure out how I can see you.. in your waking life."

You shook in his hold, but listened as he continues.

"I.. " he smirks.

"I'll be seeing you soon enough... And there's nothing my brother can do about it! I will make you mine."

He kisses you forcefully.

Your eyes widen.

------------

Your alarm goes off, beeping over and over then you punch it.
"Shut up.."

You sit up rubbing your temples.. that nightmare have you a massive headache.

But it was just a dream... Right? Then why did it feel so real?

And.. why is your neck wet?

You run to the bathroom and look in the mirror.. you looked awful.. large bags under your eyes.. your eyes bloodshot.. you haven't gotten a good night's sleep in.. at least a month?.. is that how long it's been? You couldn't remember.

Then you saw your neck and your eyes widen out of fright.

There was one large bite mark.. and black goo on your neck..

Was that dream real?!

You put some antibiotics on the mark. It burned but helped the pain, and so it wouldn't get infected.

Now you would have to wear a scarf for a while till it healed.

You left your bathroom and grabbed some clothes, next was a shower.

-------------

No matter what soap you used the black ink or whatever it was, wouldn't come off.

It was like it was stained or permanent.

You sigh and throw on your scarf to hide the mark, then you leave your bathroom.

-----------

When you entered the kitchen, there was two pancakes sitting on the table with a sticky note on the fork.

You pick it up and read it.

Dear y/n, I made you breakfast you can re-heat it in the microwave if it's cold by now. Sorry I couldn't join you for breakfast something happened at work. And you were screaming in your sleep again, you need to start taking your meds again. It's really worrying me.

-love mom.

Under the note was a small doodle of a heart.

'moms..' you think.  You didn't want to take your meds.. they made you sleep.. and you didn't want to sleep anymore.. not with him running around.

You sigh and eat your slightly warm pancakes.

--------------

You left the house, you needed some fresh air, to get out of that house....

To get away from your thoughts, you sat at a lone bench by a stop sign under a tree.

You put in your headphones and clicked on your playlist.

You kept your phone in your lap and looked to the sky... Strange... It looked exactly like the Meadows sky in your dream before it all went down hill.

Then you felt something wrapping around your leg, you gasp and look at your leg.

There was a black tendril slowly making it's way up your ankle.

You shut your eyes and shook your head, when you looked down again it was gone...

"It's okay y/n.. it's just visions! Yeah.. it's not real.."

----------

You arrived home exhausted... But you couldn't sleep.. you wouldn't sleep...

Your house was dark..  where was your mom? Shouldn't she be home by now?

"Mom?" You yell.

Silence.

You enter the kitchen and scream.

(GORE WARNING)

Your mom was being ripped in half, getting squeezed to death by large tendrils.

(LESS GORE)

And there he was laughing while doing so.

His eyes land on you and he throws her against the wall, and walks to you.

You yelp and fall on your back.

He grabs you with the tendrils holding you close to his chest.

"Gottcha!~"

End..? Hope you enjoyed. This was creepy-fun to write!
