Based on Season 3, Episode 10 "Dream a Little Dream of Me"

Prompt: "When you were in my head, what did you see?" – Dean

They got out of the Impala to find themselves in front of a large house; blue panelling with a white veranda.

"This wasn't here before," Sam commented, turning round momentarily to see the car had vanished, "Guess we're in your dream then, huh?"

"Yeah. Let's go find this son of a bitch," Dean replied, starting to walk off in the other direction.

"What if he's in the house, Dean?"

"He's not in the house Sammy, trust me, let's go"

"Then you don't mind if I take a look"

"Come on Sam! Let's go"

"How often do I get to see inside your head Dean? It's not like you ever share anything," And with that Sam was running off towards the house.

"Dammit," Dean swore and ran after him.

With some respect for Dean's privacy, Sam was waiting outside the door.

"Please don't do this Sam"

"There can be no demon behind this door that I haven't already seen." Sam raised his eyebrows at Dean and opened the door.

The hall into which he stepped was light and roomy; the sunlight dancing along the banister next to the stairs.

"Dean? Is that you?" A familiar voice called from upstairs and, quick as a flash, Dean stepped into the hall and stuffed Sam into a cupboard next to them – not noticing in his haste that he had left the door open a crack. Sam peered through and what he saw nearly broke his heart.

Sam was coming down the stairs – Dean's image of Sam. There were no scars on his skin, no worries behind his eyes. He was wearing an Armani suit and just doing up his tie.

"Don't look so worried Dean," he said, "I'll win this case and that jerk will be behind bars; you'll see."

Dean straightened Sam's tie. "I know that Sammy – you're the best lawyer there is."

"Okay, what's wrong?" Sam asked, sitting down on the stairs and looking up at Dean.

"Nothing's wrong, I'm just tired. You look good Sammy: go knock 'em dead." He leant forward and pecked Sam on the forehead – so quick that if the Sam in the cupboard hadn't been watching with rapt attention he would have missed it.

Is this what Dean dreamt about, he wondered? A world where Sam was safe from demons; where his little brother could live out a normal life with a white picket fence?

He watched as the other Sam put on his coat and reached for the front door.

"I love you Dean," he said, looking back, "You know that."

Dean grinned – a smile unlike any from reality. "Yeah, I know that Sammy."

"You're meant to say you love me too, jerk!" Sam laughed, dropping his fingers from the door handle and taking a step towards Dean.

"Hey, let's not turn this into a chick-flick moment," Dean said, trying to stare his dream down.

But Sam just grabbed both sides of his head, told Dean to shut up, and kissed him.

The Sam in the cupboard fell forward in shock and landed on the floor of the hallway.

"I've never had this dream before!" Dean yelled, near hysterical, trying to remove his 'brother's' hands from his backside, and hurtled out of the front door pulling real Sam with him.

The last thing they heard was the apparition shouting "I'll make you pie!" before getting lost in the forest.
