okay, new plot for a mystery/thriller...

I had a dream that I was... someone who'd grown up pretty much off the grid. I think I was an orphan who'd never held legal residence and lived with this kind of urban Robin Hood gang...

The building we're camped out in gets raided by a military group, some special-forces unit, and I get chased around for a while before they finally catch me and shoot me with a tranquilizer.

I wake up later in a hospital, because I was Not Exactly In Great Health, and I'm kind of drugged...

And while I'm recovering in my hospital bed, one of my friends from the group I was in sneaks into my room to tell me,

"Listen, don't worry, I'm swapping out your blood samples with mine. Everything's going to be okay."

And he sounded really rushed, but like he was doing this heroic thing... But I had no idea what he was talking about?

He was holding the vial of blood that he was going to put in place of mine for tests...

And I... tried to ask him why he was swapping out my blood, but he wouldn't tell me...

I think I asked, "...what's wrong with my blood?" and he said nothing and hurried out of the room...

So I was already worried about it, and started trying to leave... But the hospital staff didn't really allow me to go anywhere.

And what's worse is that I caught some suspicious-looking suit-and-tie guys messing around with my blood samples too...

I'd assumed they were getting samples to test for diseases and maybe run a genetics test on me... But had no idea why so many people were trying to keep that from happening.

I NEVER GOT TO FIND OUT WHAT WAS HAPPENING... I woke up before I could.

So I don't know if I was secretly... Sick, or like, someone really important... Or an alien...

I think my brain was going in a "you have mysterious, possibly magical properties" direction.

And I think this could be a neat mystery short story about an increasingly-freaked-out girl who has to run around a hospital trying to figure out what's going on...

surprise twist, it's the friend's blood that is strange and he set you up

That jerk!!
