She's across the street from a Walmart Supercenter.

There are a handful of cars scattered through the parking lot.

Oh good, civilization.

Aaaand it's closed because it's midnight on Christmas. 

Possibly the thing to do here is get out her cell phone and call her parents, so that someone in the world knows where she is, but she doesn't want to try to explain this whole thing over the phone and also it would scare them for no reason. She'll get somewhere less stress-inducing and then call them. Maybe she's even close enough to Pittsburgh that they can drive out and get her. Where is she anyway?

She's at a Walmart Supercenter. (Her phone is totally fucked.)

Oh right, because of the lightning. Honestly it's a stroke of luck her clothes are only scorched and not shreds.Maybe there's someone sleeping in their car who can drive her to a bus station or a police station or at least tell her where she is.

There is a guy sleeping in the third car she checks.

Knock knock on the window? Attempt at sad puppy eyes that's surprisingly high quality considering her eyes are featureless quicksilver like the rest of her?

The guy blinks blearily up at her, decides she’s a dream and he’s still asleep, and puts his head back down.

Knock knock. "Please? I'm lost and my phone is dead. I'll buy you dinner?"

“You’re a dream,” he informs her. “I don’t hafts get up for dreams.”

If he's dreaming and she's dreaming then who's flying the plane? The pilot, one hopes.

Maybe she should bother someone else. Are there any buildings she can see from here that have their lights on?

Nope.

She could wander around looking for a police station but she's so cold. Knock knock knock "I'm really sorry but please wake up!" If this doesn't work she'll bail and hope she can keep herself warm by jogging until she finds another person.

He groans and opens the car door.

"Thank you, sorry, can you tell me where I am and help me get to a police station or a bus station or something?"

“Uh, Uniontown. I have no idea where to find cops, I’m just passing through.” And not stupid enough to deliberately interact with cops.

That could be a lot worse! "Do you have a phone I can borrow for two minutes to tell my parents where I am?"

"Sure, persistent dream girl." He hands her his phone. It does not occur to him that annoying dream apparitions might be stymied by his lockscreen.

"Um. Can you unlock it?" If he doesn't want to unlock it she can give the emergency call feature a try.

"3-4-5-7-9-1," he mumbles grumpily. 

"Thank you so much!"

Her first call doesn't go through, which is nerve-wracking; her second goes to voicemail, which just means her mom hasn't started picking up unknown numbers. She texts "this is Samantha pick up" and tries again and that works, but the connection is terrible.

"Mom it's me, I'm at the Walmart in Uniontown, come get me! Something happened to the plane, I don't know what, I didn't see it crash and I don't think I'm injured but it's all very weird."

"Thank you!! I feel fine but uh. My skin looks weird? It's not as bad as it sounds. I think."

"I can't hear you, you're breaking up--love you too--see you soon--" the line goes dead and there's not enough signal to get another text through.

Samantha gives the man his phone back with a twenty-dollar bill wrapped around it and starts jogging back and forth in front of the Walmart to keep warm. She's scared the plane crashed and everyone else on it is dead. She's scared something is wrong with her skin. She's scared something is wrong with her brain. The guy didn't remark on her looking weird at all; he might have been being polite or she might have hit her head getting out of the wreckage of a plane crash and now she thinks she's silver and has superpowers. She feels lucid, she can add and subtract two-digit numbers in her head and get the same answer every time, the cold bites in a way cold in her dreams never has, but all of that seems like thin evidence in the face of: how did she get out of the plane? She can't even go look for the plane, she said she was at the Walmart, she needs to stay by the doors of the Walmart until her parents get here.

There is some kind of ruckus around the side of the building. 

She's gonna go check that out. It might be another human being, or a solvable problem, or information about what the fuck is going on. Or the next part of this dream plot. She walks to the corner and peeks around it. (Her attempt at stealth is not really accounting for how reflective her face is now. If there are any light sources over there, she gleams.)

There are like twenty dog-sized mice fighting with over a hundred mouse-sized arthropods of various stripes. As Samora watches they manage to knock over the dumpster they seem to be fighting over.
