A/N: You're six and a half in this imagine.
----------------------------------------------------You had been eating your dinner with your family like any other normal night. It was meatloaf and corn, with chocolate chip cookies for dessert. As soon as you took your first bite of the delicious meatloaf, the lights started to flicker. Your mom and dad brushed it off and said, "Probably the wind on the power lines outside."
Before you could even open your mouth to say, "Ok", a black smoke came in through the vents, and seemed to force itself down you mother's throat.
"Mommy!" you screeched, your voice tiny and high pitched.
"(Y/N!) Go hide in the closet!" your dad yelled as your mother turned to look at you. Her eyes were coal black, and she had an eerie smirk on her face.
You ran as fast as your tiny legs could carry you to the closet in the other room. While in there, you tried to hide even farther in the closet when you heard your dad scream, followed by a loud crash by the front door.
"You're too late," You heard your mother laugh, followed what sounded like a small firework.
"Search the house, Sammy," you heard a gruff voice yell, then shuffling past the door. You opened the door a crack, and looked around. The thought about running went through your mind, and you looked around one more time to make sure the coast was clear. You bolted out of the closet as quietly as you could. Right before you could reach the front door, someone really tall walked in front of you. The man reached down quickly, picking you up.
"Let me go!" you squeaked in fear, kicking and squirming in his grasp.
"Hey, hey, calm down, we're here to help," he spoke softly. The man had long brown hair, and was really tall. "I'm Sam."
Just then, another man came running in, a gun in his hands. You screeched when you saw it, and you kicked even harder to try and get away. The other man looked at you in confusion, then looked at his gun and quickly put it down.
"That's my brother, Dean," Sam said, trying to calm you down. "What's your name?" he asked, seeming to try to block your view of the kitchen where you last saw your mom and dad.
"(Y-y/n)," you gulped, still wary of the strange men around you. "Where did Mommy and Daddy go?"
Sam and Dean looked at each other with worry and empathy in there gaze. "Uh, they left you with us (y/n), they couldn't handle saying goodbye, so they left," Sam said, earning a glare from Dean.
"Why? And what was that smoke monster thingy?" you asked, confused why your mom and dad left you with people you've never even met.
"The 'smoke monster thingy' was... uhh... a thing some people do to clean there vents... and your mom accidentally breathed it in. Nothing bad will happen to her," Dean answered. "And your parents left you with us because they had to make sure the vents were really clean."
"Oh. Why was Daddy so scared of the smoke if it wasn't gonna hurt us?" you questioned on, a little more relaxed for getting answers, but very tired from all the sudden excitement.
"Because he didn't know it was coming through the vents now, he thought it would come down later, so it surprised him," Sam said before Dean could.
"Oh," you yawned. Normally you went to bed right after dinner.
Sam finally put you on the ground, still blocking the kitchen from view. As you let out a yawn, you held on to his hand, and leaned on him a little. You were so tired.
"Dean, you know what to do. I'm gonna go take (y/n) to the car," Sam told Dean walking out the front door to a cool black car. He opened the car door and put you inside, and turned around to go back inside.
"Wait! I don't wanna stay outside alone," you whimpered.
He turned to look over and saw Dean exiting the house. "Do you want me to stay in the back with you?" he asked. You nodded quickly.
-----------------------
*Time Skip*
-----------------------You jolted awake, crying and screaming from the nightmare you had. It was a replay of everything that happened at dinner. The smoke may have not hurt your parents, at least that's what Sam and Dean say, but it still scared the crap out of you. Sam and Dean both jumped at your sudden outburst.
"Are you ok?" they both looked over to you, Dean in the driver's seat, and Sam snuggled up next to you.
"Y-yeah, just a n-nightmare," you cried softly, still remembering every detail. You clung to Sam's shirt, trying to calm yourself down. He hugged you back, and rubbed soothing circles on your back.
"It's ok, you're fine," he repeated until you calmed down. And with that, you fell asleep again, hugging Sam. The nightmares didn't come back for the rest of the ride.
