Okay, so first things first, I've REALLY wanted someone to write one of these stories and I just can't find any. So please, I beg you to write your own story where Dean or (preferably) Sam are the others imaginary friend. Can be they were never real, or something happened to them, I don't care. Please put the words Tulpa or Imaginary in there so I can find it. Thanks.
Now some quotes that would fit this story incredibly well.
Inception: She locked away a secret, deep inside herself, something she once knew to be true... but chose to forget.
The Doctor: If something can be remembered, it can come back
Puddleglum: Suppose we have only dreamed, or made up, all those things-trees and grass and sun and moon and stars and Aslan himself. Suppose we have. Then all I can say is that, in that case, the made-up things seem a good deal more important than the real ones. Suppose this black pit of a kingdom of yours is the only world. Well, it strikes me as a pretty poor one. And that's a funny thing, when you come to think of it. We're just babies making up a game, if you're right. But four babies playing a game can make a play-world which licks your real world hollow.
Hub:"Doesn't matter if it is true or not, a man should believe in those things , because those are the things worth believing in... got that ? If you want to believe in something, then believe in it! Just because something isn't true, that's no reason you can't believe in it! "
Sam was dead.
He really didn't know how to deal with this information, but he was really and truly dead. Had been for years now.
All he wanted was a stupid razor after his broke, so naturally he went to Dean's room to borrow one of his.
And that's when he saw it sitting there. The journal.
Sam knew it was wrong to look into Deans stuff, but he never opened up to him, so maybe Sam thought maybe if he knew what was going on in his head, he could help.
The last date it had been written in was when Sam left Stanford with Dean. Weird.
But that was nowhere NEAR as weird as what the book said.
"I saw Sam today for the first time in four years. Dads still gone and I thought Sam could help me find him.
I screwed up. Sam, he's- well he's dead. He forgot his jacket in my car and I went back to give it to him and well…..
He and his girlfriend were on the ceiling. Just like mom all those years ago, and just like here, he burned.
I'm so stupid it's all my fault I should have checked I-"
Sam stopped reading there. This just didn't make any sense what so ever, I mean he'd remember dying right?
Right?
So the next step was research, and according to Google, he was buried in some crap cemetery that was by the college.
Well, what was he then? He wasn't a demon or ghost because he could cross all the salt lines, and he wasn't anything that was brought back through necromancy or anything so what was left?
After about a solid hour of thinking, Sam remembered the case were he and Dean met the ghost facers for the first time.
And he remembered the tulpa, the creature that existed simply because it was believed in hard enough.
With that theory in his head, he marched down stairs.
He and Dean had some talking to do.
*for those of you who don't know a Tulpa is basically an imagery friend that is believed in enough that it becomes real. IDK if it works, I don't believe in it but to each his own.
