Sam, Dean, and Maria are asleep in their motel room. Maria and Dean share a bed, as always; Dean faces the door and Maria faces Sam's bed. Sam stirs in his sleep, having another nightmare. He grumbles a bit and turns over, now lying on his back. He grunts more in his sleep, a bit louder this time. Maria's eyes snap open at the sound and she looks at Sam, who is still grumbling. Dean is still fast asleep as Maria sees Sam's eyes open. He looks around confusedly, but doesn't look in his older siblings' direction. Maria sighs inwardly and tries to go back to sleep.

The next morning, Dean and Maria are sitting at the little table in their motel room, gathered around their laptop and looking for their next hunt. Sam sits on his bed, drawing in a notebook and not really paying attention to Dean's words. Maria watches Sam sadly; she hasn't told him that she knows he's been having nightmares again.

"All right. We've been cruisin' some websites. I think we found a few candidates for our next gig. A fishing trawler found off the coast of Cali—its crew vanished. And, uh, we got some cattle mutilations in West Texas. Hey," Dean says. Sam finally looks up from his drawing. "Am I boring you with his hunting evil stuff?"

"No, I'm listening," Sam says, returning to his drawing. He doesn't notice Maria looking at him with concern. "Keep going."

"And, here, a Sacramento man shot himself in the head. Three times," Dean continues. He waves a hand to try to get Sam to look at him when he sees he has returned his attention to his drawing. "Any of these things blowin' up your skirt, pal?"

"Dean, leave him alone," Maria scolds him quietly. Both Dean and Sam ignore her. Sam gets up and searches through his duffle bag after studying his drawing a bit more closely.

"Wait. I've seen this."

"Seen what? What are you doing?" Dean asks, thoroughly confused. Maria just looks at Sam with concern. Sam pulls out their dad's journal and finds a picture of their family taken when he was just a baby. Mary Winchester is holding baby Sam, and John is holding a young Dean and Maria. They are standing in front of their Lawrence, Kansas home, a tree in the background; the same tree Sam drew in his notebook.

"Dean, Maria, I know where we have to go next."

"Where?" Maria asks.

"Back home—back to Kansas."

"Okay, random," Dean says. "Where'd that come from?"

"All right, um, this photo was taken in front of our old house, right?" Sam asks, showing the photo to Maria and Dean. "The house where Mom died?"

"Yeah," Maria answers, looking at her younger brother with apprehension.

"And it didn't burn down, right?" Sam continues. "I mean, not completely, they rebuilt it, right?"

"I guess so, yeah," Dean replies. "What the hell are you talkin' about?"

"Okay, look, this is gonna sound crazy but…the people who live in our old house—I think they might be in danger."

"Why would you think that?" Dean asks quickly.

"Uh…it's just, um…look, just trust me on this, okay?" Sam says. He starts to walk away, but Dean and Maria follow him.

"Wait, whoa, whoa, trust you?" Dean asks incredulously.

"Yeah," Sam replies.

"Come on, man, that's weak," Dean argues. "You gotta give us a little bit more than that."

"I can't really explain it is all."

"Well, tough. We're not going anywhere until you do," Dean counters.

"Is this about the nightmares?" Maria asks suddenly. Both Sam and Dean look at her, shocked.

"How do you know about—" Sam begins, but Maria cuts him off.

"I've heard you, Sam. You aren't exactly a quiet sleeper," she says, crossing her arms. Sam sighs and Dean waits expectantly for Sam to explain himself.

"Maria's right. I have these nightmares. And sometimes…they come true."

"Come again?" Dean says, stunned. Maria's mouth drops open; neither of the older Winchester siblings was expecting this.

"Look, Dean, Maria…I dreamt about Jessica's death—for days before it happened."

"Sam, people have weird dreams," Maria says, trying to make sense of this. She and Dean sit down on their bed. "I'm sure it's just a coincidence."

"No, I dreamt about the blood dripping, her on the ceiling, the fire, everything, and I didn't do anything about it 'cause I didn't believe it. And now I'm dreaming about that tree, about our house, and about some woman inside screaming for help. I mean, that's where it all started, you guys, this has to mean something, right?"

"I don't know," Dean says, overwhelmed. Maria says nothing, staring at the bedspread.

"What do you mean you don't know? This woman might be in danger. I mean, this might even be the thing that killed Mom and Jessica!"

"All right, just slow down, would ya?" Dean says, standing up. He begins to pace. "I mean, first you tell us that you've got the Shining? And then you tell us that we've gotta go back home? Especially when…"

"When what?" Sam asks.

"When we swore to ourselves that we would never go back there," Maria says quietly, still looking at the bedspread. Dean nods.

"Look, Maria, Dean, we have to check this out," Sam says softly, looking from his sister to his brother. "Just to make sure."

"I know we do," Dean says. Maria looks up at Dean and then over to Sam. She nods sadly.
