As previously mentioned, nothing seemed out of the ordinary at all until Dean was forced to a complete stop.
Well, technically, Dean ran directly into some unseen barrier, and ended up flat on his back staring up at the sky, too stunned to really do anything but lay there, open-mouthed and confused while rubbing absently at the slowly forming lump at the back of his head where it had hit the ground.
Sam, resisting his urge to whoop with joy and blame karma for his older brother's misfortune, moved to help Dean stand, the help rejected by the irate older man.
"See, I told you there was something abnormal here" Sam commented, as he watched his brother dust himself off.
Dean, for the most part ignored the comment, attempting to focus on the invisible wall that was in front of him.
He reached out a hand, which was quickly slapped away by Sam.
"No, dont touch it! It might be dangerous" Sam exclaimed, moving between his brother and the barrier to prevent further temptation.
Dean arched an eyebrow at the taller man.
"Fuck, Sammy, I just ran into the goddamn thing! I think if it was going to, I dont know, suck me into an alternate universe or something it would have done it by now" He moved to touch it again, giving Sam a pointed look. Sam just shrugged and moved out of the way.
Dean's hand met with no resistance as he reached out to touch the invisible barrier, there was no strange sensation, not tingling, nothing to suggest that there was anything in the least bit unusual about the blank space in front of him. He could see his hand, it had not magically disappeared, so, he took a step forward and promptly vanished.
Sam stood, gaping for a moment before his brain caught up with the situation, then launched himself at the barrier himself, only to land flat on his ass.
He quickly got to his feet and rushed toward it again, beating his fists against it and calling his brother's name to no avail. "Goddamn it, I told him not to touch the thing, I told him it was dangerous, but as usual he totally ignores me" he shouted to nobody in particular.
Meanwhile on the other side of the barrier, Dean found himself in a rather odd predicament.
After stumbling through whatever it was he had stumbled through, he found himself in what looked to be a set for a movie or television show, just out of the way enough to be hidden from everyone, but at a vantage point where he could see them. His heart stopped when he saw himself and Sam off in the distance chatting and goofing around, and the shock of that sight reminded him that he had actually left his baby brother on the other side of the, well, the whatever it was that he had walked through.
He turned, moved quickly back in the direction he had come, and attempted to go back through to no avail. Once again he found himself up against a barrier as solid as brick. This, of course, did not deter him in the slightest, and he began to hammer his fists and kick the barrier, shouting obscenities, which in turn, alerted the people on the set to the fact that there was someone there that should not have been there.
Dean realised this a few moments too late, when he turned to see several startled people staring at him like he had grown a penis in the middle of his forehead.
He stopped, smiled sheepishly at the small congregation and raised a hand.
"er...hi?" he muttered quietly...
