Coming out of your sleeping haze, arms that were once around you, shift onto their elbows, and a deep, groggy voice accompanying, "What are you doing man, it's the middle of the night."
"We have to go." Sam's voice presses, actively packing up their motel room with panicked urgency.
"What's happening?" Dean's awake, but not alarmed.
At this moment, you've slowly blinked your eyes open, the stress in the room almost radiating from Sam had caused you to wake with a start. "Dean...what's going on?"
Dean then immediately looks down to your form, the soft question leaving your throat. His eyes soften, "Sorry, sweetheart- looks like we might be leaving."
"We have to go. Right now." Sam urges, now walking out to the Impala, leaving Dean and you to pack up.
"Dean...?" You mutter, still trying to adjust to being awake at what must be around 4 AM.
"I-uh.. I don't know...I don't know," Dean mumbles, now out of bed, rushing to grab for both of your duffel bags. He rakes a hand through his hair, visibly stressed and looking around to make sure that nothing is left behind. You get up to go and help him pack, while he raises his head to shake his head, "Go wait in the car, go back to sleep, I'll get your stuff."
Albeit wanting to help him, your exhaustion speaks for you, "Okay," You resign, making your way to Baby.
This whole thing was weird to say the least. Sam had been getting these horrific nightmares, that not only wake him up in the night, but cause physical reaction. You worry for him, but Dean seemed to be taking it pretty bad. He does his best not to let it show, but you can see his concern clear as day. He's honestly afraid. Not of Sam- never of Sam, but for Sam. This is one of the few times where he has no idea what to do. And now? These nightmares keep evolving.
On top of everything else, his mind is in a whirl bouncing between his concern for you. He hated roping you into the hunting world, but he figured he could keep an eye on you. This mental tug-of-war was ruling him.
